I'd like to be able to pickle instancemethod objects mainly because I
want to be able to delay a call like ``foo(spam, badger)`` by dumping
``foo``, ``spam`` and ``badger`` to disk and loading them again later.
Sometimes the callable ``foo`` is actually a bound method, e.g.
``bar.baz``, b

Neither. pop is an instance of a class, like:

pop = X ()
pop surely is the culprit but it has arrays of objects, etc., and I

In this case I have used hasattr(obj, "__iter__") instead of
isinstance(obj, list)
(strings are iterable but do not have __iter__ method). I think hasattr
