Why do you need that test? Do you have some X that migh be a dict and
might be something else? In that case, I'd say that it's better, both
style wise and for practical reasons, to wrap your data in tagged
tuples so that you can distinguish between them easily, regardless
of their actual representation.
If, on the other hand, X should never be anything but a dict, then you
don't really need the test.
