    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))

    (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.
