This program goes through the compiler ok, although I believe it should be a syntax error:

    int main() {
      int bar;
      if(true) {
        int bar;
      }
      return 0;
    }

It is legal, as { } introduces a new scope. -Walter

Oh, I thought that duplicate local variables weren't allowed in D.
You've written it in the language specs:
"It is an error to declare a local variable that hides another local
variable in the same function"

I thought you said locals that hide other locals are an error.

I knew that used to be true in C/C++, but I thought that we were getting rid of that.  Oh well :)

You're right, my goof. I'll log it as a bug. -Walter
