Doesn't this functionality confuse matters?
If this patch is added, is there now no difference between instanceof
and is_subclass_of(). If this is the case my question is then why do
we have two methods to do the same thing?
I thought instanceof was for parent classes + interfaces.. and
is_subclass_of() was just for parent classes.
