AFAIK, Py is a complete language, which parses and processes every token 
of code.

I'm pretty sure James is trying to avoid doing that.

My preprocessor also parses and processes every token of code. I don't 
see any other way of being able to accurately determine if = is an 
assignment or operator.

Ox might be a good solution.
