This may be useful to you, but it isn't duck typing.  In fact, it
appears to be more or less the opposite, in concept.  Here, you're
checking class ancestry and gatekeeping your method calls and return
values based on that ancestry.  The thrust of duck typing, as I
understand it, is that you just ask an object to do something --
without regard to its class, and quite likely without doing a
respond_to? call first.
