Well, if set_error_handler could catch E_ERROR errors (and not bail), then errors could be changed to exceptions in user space. I already use this in the soap library to catch invalid parameters, which I beleive are only warnings. Not being able to catch exceptions on type hints will make them pretty useless to me.
Now that is a very strong statement. I consider type hints useful syntactic sugar but I don't think that it's useless if it doesn't throw an exception.
If soap is a special case because of its nature, then don't use type hints and check their type and throw an exception in user-land.
