same-name vars from different scopes

same-name vars from different scopes

[Michael Snyder]

Is there a syntax for printing/using a static variable from a different 
module, even though it's eclipsed by a more-local variable of the
same name?

According the node Variables in the manual, this should work:

   print 'file.c'::global

Surprisingly, I don't think I have ever actually done this.

There's no syntax for printing a local variable which is hidden by a
more inner definition.

In that case, I think you have to switch frames (there might be
a known bug with Ada on that subject).

Actually, I meant nested lexical scopes:

void f () {
  int x = something;
  {
     int x = something_else;
  }
}

If you in the inner scope, you can't refer directly to the outer 'x'.
You can see it with "info locals", but you can't use it in an expression.
