Hi,
object_class_dynamic_cast() checks whether a class implements
a type name, and return the class casted appropriately. This
also works with interfaces, except when an interface is
implemented multiple times (by intermediate abstract parents /
interfaces).
I had a chat with Pierrick where he said diamond graph often leads
to problems, so it is safer to not allow multiple inheritance that
way; and returning the casted class is simple enough.
I'll see how to do differently, effectively not pursuing this series.
This series factors object_class_implements_type() out of
object_class_dynamic_cast() and use it (at least the meaning
seems clearer to me when reviewing).
I could get it working with object_class_foreach() but for
some reason fail at writing a proper test. Posting the last
patch as RFC so we can discuss it on the list.

Phil.
