There's one potential breakage that I see here: the Decimal.__pow__ function has different semantics in the new version of Decimal (nonintegers are now allowed as exponents; some previous restrictions on argument sizes no longer exist), so backporting the new version of __pow__ might cause difficulties. In particular, some cases of three-argument pow that previously worked (giving arguably nonsensical results) will now raise an exception. To be honest, I'd be quite surprised to find that *anyone* was using the three-argument pow, but perhaps we should be careful here? Mark
