If I make a product using Python, that means someone gonna be able to

(no misunderstanding, I am a person supporting Open Source, but you know, 
if you work for other companies, they may not like the idear)

Warning: It probably won't work.  But it's worth a try.

Failing that, you can just use the `dis' module on the functions and
work out what they do by hand, which is not very hard, but very


very few people approach me in real life and insist on proving they are
drooling idiots.                         -- Erik Naggum, comp.lang.lisp
