Almost everything in Python is an object - especially in V2.2!
[ But note that an object is not necessarily the same thing
as an instance of a class ]

It contains the list of modules currently imported.

Not a lot! Python uses that list, its not really for programmers
to mess with unless you really know what you're doing - and even
then you probably shouldn't!
You should only add to the list by importing your module as in:

You can do spome freaky things to python's internal
operations, but you probably shouldn't...
> import test
> import sys
> sys.modules['test'] = test
Is redundant since the import already did that for you.
