If my program needed to know if an object is iterable, it would be tempting to
define and call the following function instead of using
collections.abc.Iterable:

Maybe this would have been more appropriate as a question on StackOverflow:
What is the proper way of asking if an object is iterable if it does not
support the iterator protocol but does support the old getitem protocol? One
might argue that it is
