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.
