I would not assert this does not happen, but if it does there were some 
bad design decisions that would allowed this to occur.

I would have expected functions that were so dependent would be within a 
single module where one would: from modulex import sub_module ...  The 
specific function would not be named but would be readily executable 
because its dependency would be present.  This definitely does not seem 
to be the way I have seen it in my limited experience.

I would caution you that I am too new to Python to pretend to be an 
authority even on its basic features at this time.  Perhaps this will 
attract a much more knowledgeable comment from someone following this 
thread.
