    Code to deal with macros, namely with: * Compilation of macro definitions * Expansion of macro applications

    Code to deal with macros, namely with: * Compilation of macro definitions * Expansion of macro applications

    Say we have in a class C:

    def foo[T](xs: List[T]): T = macro fooBar

    Then fooBar needs to point to a static method of the following form:

    def fooBar[T: c.WeakTypeTag] // type tag annotation is optional (c: scala.reflect.macros.blackbox.Context) (xs: c.Expr[List[T]]) : c.Expr[T] = { ... }

    Then, if foo is called in qual.foo[Int](elems), where qual: D, the macro application is expanded to a reflective invocation of fooBar with parameters:

    (simpleMacroContext{ type PrefixType = D; val prefix = qual }) (Expr(elems)) (TypeTag(Int))
