That's true. I'd still be reluctant to start supporting operations like Decimal('1.2') + 0.71, though. At least comparisons have the nice feature that the return type is unambiguous. > > I'm +0 to allow these comparisons, being "Decimal(1) < .3" the same as > "Decimal(1) < Decimal.from_float(.3)" Yes, I should have clarified that those are exactly the semantics I'm proposing.
