Thank you both for fixing the first thing.

Returning the address of a static variable defined inside a pure function? I
don't see the purpose of this. It smells.

But this need is probably uncommon, and when this needs arises you are able to
move the definition of such variable inside the debug:


pure int foo(int x) {
    debug {
        static int y = 10;
    }
    return x;
}
void main() {}

Maybe Walter is willing to comment on this, but I think I will open another
report for this.
