Pushed!

I find that so much better, easier to understand and maintain. There is
no question anymore what that predicate can possibly be (and the comment
was wrong, I'm tempted to say of course), we have compile-time support
with an exhaustive switch. We got rid of that void * before that. And so
on. We even spared a word in the struct :-).

Thanks for doing that!
