  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.

### Abstract Value Members

1.  abstract def atOwner[T](tree: blackbox.Context.Tree, owner: blackbox.Context.Symbol)(op: => T): T

   Temporarily pushes the given tree onto the recursion stack, and then calls `atOwner(symbol)(trans)`.

2.  abstract def atOwner[T](owner: blackbox.Context.Symbol)(op: => T): T

   Temporarily pushes the given symbol onto the owner stack, creating a new local typer, invoke the given operation and then rollback the changes to the owner stack.

3.  abstract def currentOwner: blackbox.Context.Symbol

   Returns the symbol currently on the top of the owner stack.

   Returns the symbol currently on the top of the owner stack. If we're not inside any `atOwner` call, then macro application's context owner will be used.

4.  abstract def default(tree: blackbox.Context.Tree): blackbox.Context.Tree

   Calls the default transformer on the given tree.

   Calls the default transformer on the given tree. Default transformer = recur into tree's children and assemble the results.

   Definition Classes
     TransformApi
5.  abstract def recur(tree: blackbox.Context.Tree): blackbox.Context.Tree

   Calls the current transformer on the given tree.

   Calls the current transformer on the given tree. Current transformer = argument to the `transform` call.

   Definition Classes
     TransformApi
6.  abstract def typecheck(tree: blackbox.Context.Tree): blackbox.Context.Tree

   Typechecks the given tree using the local typer currently on the top of the owner stack.

   Typechecks the given tree using the local typer currently on the top of the owner stack. If we're not inside any `atOwner` call, then macro application's callsite typer will be used.
