	I don't think this is the case.  Adding a type that makes my
life easier for my code (I hate hate hate _foreach() functions) and for
the code of others is a good thing.
	In no way am I proposing "Replace all current API with GIterator
for 2.(x>2)".  This isn't feasable.  It only really makes sense for a
small set of the API (eg, gtk_container_iterate_children() returning a
GValueIterator provides more information than the GList of
gtk_container_get_children()).  Even then, I haven't included such API
in my patches because I'm not sure it would be accepted.
	However, new API can and should take advantage of such a thing.
We've discussed it already for GtkTreeSelection.  A list is a list, and
an iterator is a different beast.  Folks work with lists and iterators
in Python, Java, C++, and elsewhere without worrying.  I don't think the
complexity would really increase for the user.
