Dan's hint is the way to go nevertheless.  However, it is still not
possible to actually use the module object on the top-level (i.e.,
while module a.py is read).  So, you must delay any access to module
b until everything is fully loaded -- for example, by wrapping the
access in a function which is called from the main program.

On the other hand, the above code was for debugging purposes I
assume.  So maybe there's no real problem anyway because all your
uses of module b are wrapped in functions/methods anyway.

Tschö,
Torsten.
