Decimal is ideally low-level (it's a number), it's just that it has a complicated high-level implementation :) But we can't use Decimal by default, for the obvious reason (performance impact that threatens to contaminate other parts of the code through operator application). > Of all the > possibilties that offer decent arithmetic support, timedelta is > probably the one currently most suited to being pushed down to the os > level, although decimal.Decimal is also a contender if backed up by > Stefan's C implementation. I'm -1 on using timedelta. This is a purity proposition that will make no sense to the average user. By the way, datetimes are relative too, by the same reasoning.
