On the test that probably puts my change in the most positive light possible: "x = 0; while x < 50000000: x = x + 1", it achieves about a 50% increase in speed. More normal integer-heavy things seem to be at most 20% faster.

And you have to ask yourself -- how integer-heavy does typical Python code get?

Most Python code I write deals with higher-level things most of the time -- strings, lists, dicts, class instances.
