I had wondered about that. The wording of the quiz says "class", but I
figure that:
a) Given the number of modules-as-namespaces over classes-as-
namespaces, a good solution to the problem allows module stops along
the way, and thus
b) If you're going to allow non-classes along the way, you generally
want the "resolve this as though I typed it" functionality, which may
end in constants.

BUT...if the quiz has the wrinkle that only Classes should be returned
(and thus you should get  nil for the cases above), that would be
interesting to program, too.
