Sure it does, if you have, for example:

void bar() {
  static void foo();
  foo();
}

void bar1() {
  static int foo();
  foo();
}

void bar2() {
  static int foo(int);
  int a = foo(3);
}
foo() {}

This compiles.

I see nothing that gives me the ability to know that any particular DECL
is declared inside a particular function.

Perhaps someone might need to write different code or do something else
different per function based on the local declarations?  Does THIS make
sense?
