Not only that. IMO the primary problem was related to the fact the "patch"
was too big to be reviewed. Unfortunately it was my first attempt, and
having worked alone I introduced too much optimizations and (heavy) changes
to the code. An incremental approach should have worked better, albeit I
believe that such drastic move from the consolidated bytecodes to the new
wordcodes would have produced strong resistance anyway.

This, specifically, was an experiment that I made with WPython 1.1, which I
recommend to do not follow. There are other, more general, ways to speedup
the execution when dealing with integers.
