[docs] [issue18558] Iterable glossary entry needs clarification

[Stephen Paul Chappell]

Stephen Paul Chappell added the comment:

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:

    def iterable(obj):
        try:
            iter(obj)
        except TypeError:
            return False
        return True

Something tells me that is not what the author of collections.abc.Iterable intended.
