Not really.  You could (as another poster suggests) make an object with
some number of dynamically created attributes, and call such an object
something like 'M' (for magic)...

M.name
M.name2
etc.

An interesting feature request would be:
Allow properties to be assigned to modules after module instantiation,
coupled with the ability to get the current module.

With those two features, then what you want is possible, though those
two features /aren't/ going to make it into Python 2.4, it it would take
quite a bit of work to make it happen in Python 2.5.
