Just closed issue 7323 as a duplicate of this one. I think this issue is worth reopening: with the backport of the py3k correctly rounded string <-> float conversions, there might now be a reasonable way to rewrite Decimal.__hash__ so that it's consistent with float.__hash__. Then we can make Decimal-to-float comparisons behave correctly and clear up this mess. I'd still be uncomfortable with allowing Decimal-to-float comparisons in 2.x but not in 3.x. Maybe they could be permitted in 3.x too?
