(4) Do the following to unapplied methods used as values: (4.1) If the method has only implicit parameters pass implicit arguments (4.2) otherwise, if `pt` is a function type and method is not a constructor, convert to function by eta-expansion, (4.3) otherwise, if the method is nullary with a result type compatible to `pt` and it is not a constructor, apply it to () otherwise issue an error (5) Convert constructors in a pattern as follows: (5.1) If constructor refers to a case class factory, set tree's type to the unique instance of its primary constructor that is a subtype of the expected type. (5.2) If constructor refers to an extractor, convert to application of unapply or unapplySeq method.

   (6) Convert all other types to TypeTree nodes. (7) When in TYPEmode but not FUNmode or HKmode, check that types are fully parameterized (7.1) In HKmode, higher-kinded types are allowed, but they must have the expected kind-arity (8) When in both EXPRmode and FUNmode, add apply method calls to values of object type. (9) If there are undetermined type variables and not POLYmode, infer expression instance Then, if tree's type is not a subtype of expected type, try the following adaptations: (10) If the expected type is Byte, Short or Char, and the expression is an integer fitting in the range of that type, convert it to that type. (11) Widen numeric literals to their expected type, if necessary (12) When in mode EXPRmode, convert E to { E; () } if expected type is scala.Unit. (13) When in mode EXPRmode, apply AnnotationChecker conversion if expected type is annotated. (14) When in mode EXPRmode, apply a view If all this fails, error

    synthesize and type check a PartialFunction implementation based on the match in `tree`

    synthesize and type check a PartialFunction implementation based on the match in `tree`

    `param => sel match { cases }` becomes:

    new AbstractPartialFunction[$argTp, $matchResTp] { def applyOrElse[A1 <: $argTp, B1 >: $matchResTp]($param: A1, default: A1 => B1): B1 = $selector match { $cases } def isDefinedAt(x: $argTp): Boolean = $selector match { $casesTrue } }

    TODO: it would be nicer to generate the tree specified above at once and type it as a whole, there are two gotchas:

    - matchResTp may not be known until we've typed the match (can only use resTp when it's fully defined),
      - if we typed the match in isolation first, you'd know its result type, but would have to re-jig the owner structure
      - could we use a type variable for matchResTp and backpatch it?
    - occurrences of `this` in `cases` or `sel` must resolve to the this of the class originally enclosing the match, not of the anonymous partial function subclass

    an alternative TODO: add partial function AST node or equivalent and get rid of this synthesis --> do everything in uncurry (or later) however, note that pattern matching codegen is designed to run *before* uncurry

    Synthesize and type check the implementation of a type with a Single Abstract Method

    Synthesize and type check the implementation of a type with a Single Abstract Method

    `{ (p1: T1, ..., pN: TN) => body } : S`

    expands to (where `S` is the expected type that defines a single abstract method named `apply`)

    `{ def apply$body(p1: T1, ..., pN: TN): T = body new S { def apply(p1: T1, ..., pN: TN): T = apply$body(p1,..., pN) } }`

    If 'T' is not fully defined, it is inferred by type checking `apply$body` without a result type before type checking the block. The method's inferred result type is used instead of T`. [See test/files/pos/sammy_poly.scala]`

    The `apply` method is identified by the argument `sam`; `S` corresponds to the argument `samClassTp`, and `resPt` is derived from `samClassTp` -- it may be fully defined, or not...

    The function's body is put in a method outside of the class definition to enforce scoping. S's members should not be in scope in `body`.

    The restriction on implicit arguments (neither S's constructor, nor sam may take an implicit argument list), is largely to keep the implementation of type inference (the computation of `samClassTpFullyDefined`) simple.

    NOTE: it would be nicer to not have to type check `apply$body` separately when `T` is not fully defined. However T must be fully defined before we type the instantiation, as it'll end up as a parent type, which must be fully defined. Would be nice to have some kind of mechanism to insert type vars in a block of code, and have the instantiation of the first occurrence propagate to the rest of the block.

     However reification does need annotation definitions to proceed. Unfortunately, AnnotationInfo doesn't provide enough info to reify it in general case. The biggest problem is with the "atp: Type" field, which cannot be reified in some situations that involve locally defined annotations. See more about that in Reifiers.scala.

     That's why the original tree gets saved into `original` field of AnnotationInfo (happens elsewhere). The field doesn't get pickled/unpickled and exists only during a single compilation run. This simultaneously allows us to reify annotations and to preserve backward compatibility.
