Then you'd be asking if the object _acts like_ (quacks like) an
enumerable, would you not? Why wrap that in a begin....rescue clause
and only spot it after the fact when you can catch it ahead of time?
Certainly it doesn't violate duck-typing to ask what an object acts
like (which is what imposing conditions on an object would be doing)?!
