  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))

# MacroImplBinding

###
Companion object MacroImplBinding

#### case class MacroImplBinding(isBundle: Boolean, isBlackbox: Boolean, className: String, methName: String, signature: List[List[Fingerprint]], targs: List[Global.Tree]) extends Product with Serializable

Represents all the information that a macro definition needs to know about its implementation. Includes a path to load the implementation via Java reflection, and various accounting information necessary when composing an argument list for the reflective invocation.

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
