You can stop right there:  at this point you have to be prepared to handle
every exception, as the underlying getattr(frob, "mumble") lookup can
execute any code whatsoever (especially if frob defines a __getattr__ hook).
There's nothing else useful to be said about this, including:

> At some point you do know the type.  You just have to infer it.

At least you've reduced it to a simpler problem <wink>.
