There's a lot of old code that assumes that a module is an atom and
nothing else. To fully support modules-as-a-datatype, there should be
a new type test is_module(X), rather than temporarily inserting tests
for tuple-ness (which have to be changed when module objects are no
longer represented as tuples).
