Hi!

Can't we fix it? I mean, when we unset property on an object, we're
still keeping the definition in the class, right? Can't we use it?

Can't we assume $a->x is still "int" here in a way - I mean, we'd still
have to allow for the possibility of null, but if we say that any one
could be null it's just one easy check, so it won't hurt performance too
much, not?
