[Pyrex] Using pyrex to hide source.

[jbi130 at yahoo.com]

I've noticed that with some little changes to some of my pure Python
modules I can compile them with pyrex into C and they pretty much work
the same.

Is this a reasonable method to hide some of my more critical modules?

Yes, I know a license is the best way to solve this issues.  I'm
mainly wondering if I'll run into any catches by doing this with
pyrex.

Thanks.
