    A motley collection of the state and loosely associated behaviour of the type checker.

    A motley collection of the state and loosely associated behaviour of the type checker. Each `Typer` has an associated context, and as it descends into the tree new `(Typer, Context)` pairs are spawned.

    Meet the crew; first the state:

    - A tree, symbol, and scope representing the focus of the typechecker
    - An enclosing context, `outer`.
    - The current compilation unit.
    - A variety of bits that track the current error reporting policy (more on this later); whether or not implicits/macros are enabled, whether we are in a self or super call or in a constructor suffix. These are represented as bits in the mask `contextMode`.
    - Some odds and ends: undetermined type parameters of the current line of type inference; contextual augmentation for error messages, tracking of the nesting depth.

    And behaviour:

    - The central point for issuing errors and warnings from the typechecker, with a means to buffer these for use in 'silent' type checking, when some recovery might be possible.
    - `Context` is something of a Zipper for the tree were are typechecking: it `enclosingContextChain` is the path back to the root. This is exactly what we need to resolve names (`lookupSymbol`) and to collect in-scope implicit definitions (`implicitss`) Supporting these are `imports`, which represents all `Import` trees in in the enclosing context chain.
    - In a similar vein, we can assess accessibility (`isAccessible`.)

    More on error buffering: When are type errors recoverable? In quite a few places, it turns out. Some examples: trying to type an application with/without the expected type, or with/without implicit views enabled. This is usually mediated by `Typer.silent`, `Inferencer#tryTwice`.

    Initially, starting from the `typer` phase, the contexts either buffer or report errors; afterwards errors are thrown. This is configured in `rootContext`. Additionally, more fine grained control is needed based on the kind of error; ambiguity errors are often suppressed during exploratory typing, such as determining whether `a == b` in an argument position is an assignment or a named argument, when `Inferencer#isApplicableSafe` type checks applications with and without an expected type, or when `Typer#tryTypedApply` tries to fit arguments to a function type with/without implicit views.

    When the error policies entail error/warning buffering, the mutable ReportBuffer records everything that is issued. It is important to note, that child Contexts created with `make` "inherit" the very same `ReportBuffer` instance, whereas children spawned through `makeSilent` receive a separate, fresh buffer.

25.  abstract class ContextReporter extends Reporter

    A reporter for use during type checking.

    A reporter for use during type checking. It has multiple modes for handling errors.

    The default (immediate mode) is to send the error to the global reporter. When switched into buffering mode via makeBuffering, errors and warnings are buffered and not be reported (there's a special case for ambiguity errors for some reason: those are force to the reporter when context.ambiguousErrors, or else they are buffered -- TODO: can we simplify this?)

    When using the type checker after typers, an error results in a TypeError being thrown. TODO: get rid of this mode.

    To handle nested contexts, reporters share buffers. TODO: only buffer in BufferingReporter, emit immediately in ImmediateReporter

    A term of one of the following shapes:

    Ident(<term macro>) Select(<any qualifier>, <term macro>) TypeApply(<any of the above>, <targs>) Apply(...Apply(<any of the above>, <args1>)...<argsN>)

    ###### Macro expansion

    First of all `macroExpandXXX`: 1) If necessary desugars the `expandee` to fit into the default expansion scheme that is understood by `macroExpandWithRuntime` / `macroExpandWithoutRuntime`

    Then `macroExpandWithRuntime`: 2) Checks whether the expansion needs to be delayed 3) Loads macro implementation using `macroMirror` 4) Synthesizes invocation arguments for the macro implementation 5) Checks that the result is a tree or an expr bound to this universe

    Finally `macroExpandXXX`: 6) Validates the expansion against the white list of supported tree shapes 7) Typechecks the result as required by the circumstances of the macro application

    If -Ymacro-debug-lite is enabled, you will get basic notifications about macro expansion along with macro expansions logged in the form that can be copy/pasted verbatim into REPL.

    If -Ymacro-debug-verbose is enabled, you will get detailed log of how exactly this function performs class loading and method resolution in order to load the macro implementation. The log will also include other non-trivial steps of macro expansion.

    returns

      the expansion result if the expansion has been successful, the fallback tree if the expansion has been unsuccessful, but there is a fallback, the expandee unchanged if the expansion has been delayed, the expandee fully expanded if the expansion has been delayed before and has been expanded now, the expandee with an error marker set if the expansion has been cancelled due malformed arguments or implementation the expandee with an error marker set if there has been an error

    1) Enter methods such as enterGetterSetter are called from Namer with a tree which may generate further trees such as accessors or implicit wrappers. Some setup is performed. In general this creates symbols and enters them into the scope of the owner.

    2) addDerivedTrees is called from Typer when a Template is typed. It completes the job, returning a list of trees with their symbols set to those created in the enter methods. Those trees then become part of the typed template.

    Marks a tree that has been adapted by typer and sets the original tree that was in place before.

    Keeping track of the original trees were is an important feature for some compiler plugins (like Scalameta) and the incremental compiler (Zinc). In both cases, adapting trees loses information in some sense and do not allow external tools to capture some information stored in user-defined trees that are optimized away by early phases (mostly, typer).

    See how the absence of this attachment blocks Zinc: https://github.com/sbt/zinc/issues/227. Related: https://github.com/scala/scala-dev/issues/340.

    This attachment is, at the moment, only used to keep track of constant-folded constants. It has a generic wording in the hope that in the future can be reused in the same context to keep track of other adapted trees.

    Generates copy methods for case classes.

    Generates copy methods for case classes. Copy only has defaults on the first parameter list, as of scala/bug#5009.

    The parameter types of the copy method need to be exactly the same as the parameter types of the primary constructor. Just copying the TypeTree is not enough: a type `C` might refer to something else *inside* the class (i.e. as parameter type of `copy`) than *outside* the class (i.e. in the class parameter list).

    One such example is t0054.scala: class A { case class B(x: C) extends A { def copy(x: C = x) = ... } class C {} } (1) (2)

    The reference (1) to C is `A.this.C`. The reference (2) is `B.this.C` - not the same.

    This is fixed with a hack currently. `Unapplies.caseClassCopyMeth`, which creates the copy method, uses empty `TypeTree()` nodes for parameter types.

    In `Namers.enterDefDef`, the copy method gets a special type completer (`enterCopyMethod`). Before computing the body type of `copy`, the class parameter types are assigned the copy method parameters.

    This attachment class stores the copy method parameter ValDefs as an attachment in the ClassDef of the case class.

    Without any restrictions on macro expansion, macro applications will expand at will, and when type inference is involved, expansions will end up using yet uninferred type params.

    For some macros this might be ok (thanks to TreeTypeSubstituter that replaces the occurrences of undetparams with their inferred values), but in general case this won't work. E.g. for reification simple substitution is not enough - we actually need to re-reify inferred types.

    Luckily, there exists a very simple way to fix the problem: delay macro expansion until everything is inferred. Here are the exact rules. Macro application gets delayed if any of its subtrees contain: 1) type vars (tpe.isInstanceOf[TypeVar]) // [Eugene] this check is disabled right now, because TypeVars seem to be created from undetparams anyways 2) undetparams (sym.isTypeParameter && !sym.isSkolem)

     Transforms parameters lists of a macro impl.

     Transforms parameters lists of a macro impl. The `transform` function is invoked only for WeakTypeTag evidence parameters.

     The transformer takes two arguments: a value parameter from the parameter list and a type parameter that is witnesses by the value parameter.

     If the transformer returns a NoSymbol, the value parameter is not included from the result. If the transformer returns something else, this something else is included in the result instead of the value parameter.

     Despite of being highly esoteric, this function significantly simplifies signature analysis. For example, it can be used to strip macroImpl.paramss from the evidences (necessary when checking def <-> impl correspondence) or to streamline creation of the list of macro arguments.
