seems to be most used at this time.

On the horizon, Python CVS's nondist/sandbox/decimal/ directory contains a
first-cut implementation of IBM's proposal for decimal arithmetic.  The IBM

I don't think this will make it into Python 2.3 -- although it might, if
people volunteered enough work to move it along quickly.
