I can't return tuples. I have to wrap them in a struct. If I do that, then I can't index the struct as if it were a real tuple. Okay, then I use 'alias this', and I end up with this struct that exists for no purpose other than to get around a silly limitation in the type system. Well, geez! Why not just make tuples first-class?
