Ah, ok. It would be somewhat confusing, though, that __module__ is
sometimes a module object, and sometimes a string (it certainly confused
me).

That remains to be seen in practice. Currently, modules are explicitly
cleared at shutdown. I think any cycle with an object implementing
__del__ will keep loads of modules alive, noncollectable for GC.
