Yes.

Unless the code does "from oldmodule import Liver" or some equivalent 
thereof, it's going to be newmodule.Liver.  This also applies to things 
like super(Liver,self) -- *all* globals used in newmodule are going to be 
newmodule's globals, not oldmodule.

There are some minor limitations, however, compared to a "perfect" module 
inheritance implementation.  The docs'll tell you all about them.
