I'd think it'd basically just say "hey compiler, make sure whatever i throw at this method contains Parents in one form or another"

amoralis, Because you're again killing the typesafety. I've seen quite some code snippets that relied on generics to find "wrong object type inserted" exceptions.

If the method in question operates on the param as Parent, what harm could there be?
It'd provide exactly the level of type safety i desire.
(but WOW is that ugly and verbose syntax..)
