This is very unlikely to speed things up as much as you expect.  I've
never produced accurate numbers, but I'm fairly sure Python's runtime
is dominated by locating applicable methods, not the dispatch loop in
ceval.c.  If you could analyse a program sufficently to compute (some
of) these methods at compile time, *then* you might start to see a
real speed up (especially if this let you unbox some integers &
floats).

Of course, this is intuition about performance, so probably wrong.
Buyer beware.

Cheers,
