You wouldn't *need* typecasts. It's a pointer and the instance it is pointing to will be initialized by the subroutine you're calling. And that one *knows* the size of the class it created. So there's typecast involved at all, if used correctly. And stop calling me clueless, please. Just because you do not understand what I write, doesn't exactly mean, I am the one who has no clue.
