  EXPERIMENTAL

  EXPERIMENTAL

  The base package for Scala macros.

  Macros are functions that are called by the compiler during compilation. Within these functions the programmer has access to compiler APIs. For example, it is possible to generate, analyze and typecheck code.

  See the Macros Guide on how to get started with Scala macros.

  EXPERIMENTAL

  EXPERIMENTAL

  The refinement of scala.reflect.api.Universe for the use by macro writers.

  This universe provides mutability for reflection artifacts (e.g. macros can change types of compiler trees, add annotation to symbols representing definitions, etc) and exposes some internal compiler functionality such as `Symbol.deSkolemize` or `Tree.attachments`.

   Collects all the symbols defined by subtrees of `tree` that are owned by `prev`, and then changes their owner to point to `next`.

   This is an essential tool to battle owner chain corruption when moving trees from one lexical context to another. Whenever you take an attributed tree that has been typechecked under the Context owned by some symbol (let's call it `x`) and splice it elsewhere, into the Context owned by another symbol (let's call it `y`), it is imperative that you either call `untypecheck` or do `changeOwner(tree, x, y)`.

   Since at the moment `untypecheck` has fundamental problem that can sometimes lead to tree corruption, `changeOwner` becomes an indispensable tool in building 100% robust macros. Future versions of the reflection API might obviate the need in taking care of these low-level details, but at the moment this is what we've got.

    If this symbol is a skolem, its corresponding type parameter, otherwise the symbol itself.

    If this symbol is a skolem, its corresponding type parameter, otherwise the symbol itself.

    To quote Martin Odersky, skolems are synthetic type "constants" that are copies of existentially bound or universally bound type variables. E.g. if one is inside the right-hand side of a method:

        def foo[T](x: T) = ... foo[List[T]]....

    the skolem named `T` refers to the unknown type instance of `T` when `foo` is called. It needs to be different from the type parameter because in a recursive call as in the `foo[List[T]]` above the type parameter gets substituted with `List[T]`, but the type skolem stays what it is.

    The other form of skolem is an existential skolem. Say one has a function

        def bar(xs: List[T] forSome { type T }) = xs.head

    then each occurrence of `xs` on the right will have type `List[T']` where `T'` is a fresh copy of `T`.

    Like `setType`, but if this is a previously empty TypeTree that fact is remembered so that `untypecheck` will snap back.

    \@PP: Attempting to elaborate on the above, I find: If defineType is called on a TypeTree whose type field is null or NoType, this is recorded as "wasEmpty = true". That value is used in ResetAttrsTraverser, which nulls out the type field of TypeTrees for which wasEmpty is true, leaving the others alone.

    `untypecheck` (or `resetAttrs` in compiler parlance) is used in situations where some speculative typing of a tree takes place, fails, and the tree needs to be returned to its former state to try again. So according to me: using `defineType` instead of `setType` is how you communicate that the type being set does not depend on any previous state, and therefore should be abandoned if the current line of type inquiry doesn't work out.

    A creator for existential types. This generates:

        tpe1 where { tparams }

    where `tpe1` is the result of extrapolating `tpe` with regard to `tparams`. Extrapolating means that type variables in `tparams` occurring in covariant positions are replaced by upper bounds, (minus any SingletonClass markers), type variables in `tparams` occurring in contravariant positions are replaced by upper bounds, provided the resulting type is legal with regard to stability, and does not contain any type variable in `tparams`.

    The abstraction drops all type parameters that are not directly or indirectly referenced by type `tpe1`. If there are no remaining type parameters, simply returns result type `tpe`.
