### Abstract Value Members

1. #### abstract def Expr[T](tree: blackbox.Context.Tree)(implicit arg0: blackbox.Context.WeakTypeTag[T]): blackbox.Context.Expr[T]

   A shorthand to create an expr.

   A shorthand to create an expr.

   Unlike the conventional expr factory, which requires a scala.reflect.api.TreeCreator, this one accepts a regular tree, but the resulting exprs are unable of being migrated to other universes/mirrors (the functionality normally not needed for macros, since there is only one compile-time universe and only one compile-time mirror).

2. #### abstract def TypeTag[T](tpe: blackbox.Context.Type): blackbox.Context.TypeTag[T]

   A shorthand to create a type tag.

3. #### abstract def WeakTypeTag[T](tpe: blackbox.Context.Type): blackbox.Context.WeakTypeTag[T]

   A shorthand to create a weak type tag.

   A shorthand to create a weak type tag.
