Ah, I see what you are saying. I thought you were saying that
>>> sympify("a = b**2")
would define b as a symbol. But rather, what I can do is something like
>>> #Return raw Python code
.... my_parser("a = b**2")
"sympify('b', locals=locals())
a = b **2 "

I've just gotten back to school, so probably won't be doing much work over
the next week. I'll notify you when I add new major features.
