I did: the code can be seen at: http://svn.python.org/view/sandbox/trunk/decimal/decimal_in_c/ This code defines a Deccoeff type as above, providing base 10 natural number arithmetic, along with a skeletal _Decimal type. The work on Deccoeff is pretty much complete, but the _Decimal type is only just a beginning; the original intent was to slowly translate the Decimal code into C and move it into the _Decimal type. The code was working a few months ago (with all Decimal tests passing), but there have been some changes and bugfixes since then. I might try to resurrect that code, dropping the _Decimal type and just concentrating on Deccoeff.
