And speaking for myself, I think it's a shame we ducked out of this one. It
wasn't possible to standardize arithmetic with 1970s languages like C and
SQL because of the sheer variety (and slowness) of hardware, but for a 2000s
language, the sights have been set too low.

Most people will be implementing decimal in software anyway, so there are
very few good excuses for implementations to differ.
