I'm really only talking about:
void a() {
int x;
}

And of course:
void a() {
bool state;
...
if (state) { }
}

I'd like the warnings to be individually selectable, just like in GCC.

Btw, here's a trick question, should the compiler warn about this case?

void main() {
    new Foo();  // or even Foo foo = new Foo;
}

:p
