I was saying that it would be nice if the following were true:

    >>> encodings.__module__
    <module 'encodings' from 'C:\python25\lib\encodings\__init__.pyc'>

That would make it easier for functions inside a module to pass around
references to the module namespace (I've had the need to do so before,
and have ended up using sys.modules[__name__], but that doesn't always
work).

So what if it is a circular reference (module references dict which
references module), we've got a GC which handles cycles just fine (when
users try not to be too smart).
