Module/namespace question

[Matthew]

Hi,

I'm working on a small aplication which allows various lexicons (stored 
in their own modules) to be snapped into a parser to extract varying 
information from files. As different users will be writing their own 
lexicons, I'm wondering about namespace conflicts when the same vaiable 
may be defined in differing ways. From my newbie experiments, this 
doen't seem to be an issue as the variable changes references as the 
different modules are imported. Are there any dangers in this approach?
Any help/hints/examples would be greatly appreciated. Thanks, matthew.

BTW, thanks to Greg Ewing for his very cool Plex.
