[Issue 12578] Allow local function overloading

[via Digitalmars-d-bugs]

--- Comment #7 from Kenji Hara <k.hara...@gmail.com> ---
One more issue which has same root is a mutual call of local functions.

void test() {
  void foo() { bar(); } // error, bar not defined
  void bar() { foo(); } // ok
}

My proposal in comment#5 could resolve the case with same way.
