Re: Local static variables must have unique names within a function's scope.

Fortunately this is not the case.  However, the static variable case is
annoying, and it's actually one case of a larger problem:

        void main() {
                foreach (i; 0 .. 10) {
                        struct S {
                                int x;
                        }
                        auto s = S(i);
                }
                foreach (i; 11 .. 20) {
                        struct S { // <---- this is line 9
                                int y;
                        }
                        auto s = S(i);
                }
        }

The compiler says:

        test.d(9): Error: declaration S is already defined in another scope in 
main

even though the respective scopes of the declarations are disjoint. IMO,
this is a needless, arbitrary restriction. Worse yet, the compiles ICEs
after this, so I filed a bug:
