Well, I didn't really decide anything. I suggested that if the
developers of Decimal preferred it, it might be better if Decimal did
not implement the Real ABC, and Raymond said he indeed preferred it.
Since this reduces the usefulness of numeric.Real, I'm somewhat
disappointed in this outcome (as I imagine you are). However, Decimal
has very little of my own sweat in it, and a lot of Raymond, Facundo
(and others, including Mark), and the ABC thing is still somewhat
experimental, so it wouldn't make sense for me to impose my ideas onto
Decimal unilaterally, and I'm sure Raymond etc. have their reasons.
