What about and overload of remove() like this:
bool remove(in T key, out U value);

If the element was present, it's returned in "value", so you can
manipulate it. I thought about just returning a pointer:
U* remove(in T key);

But I guess that pointer would point to the element stored in the the AA
private data, but that element was just removed, so bad things would
happen, that's why the only option is to copy the data, right?
