So there was a discussion back in April [0] about the lack of an "iterable"
predicate, which Pascal pointing out that the intention may be to use
"isinstance(obj, Iterable)" instead. That seems inconsistent with the
existence of collections.Callable (so, isinstance(obj, Callable) instead of

Which direction is this more likely to be resolved? Should I write
iterable(obj) or expect callable(obj) to be deprecated?
