Remember all that Decimal is a first step to a Money data type, which for
example, could deal with this.

It's clear to me now that it's better to build a Money data type over
Decimal. When I proposed a pre-PEP for Money, that was clear to others, and
that's why I was "redirected" to work in Decimal.
