We must do better than Ruby: support arbritrary precision! :-D
Seriously, I do consider that a necessary requirement for the PEP (which
the Decimal type actually meets). I don't want to deal with
this issue *again* in my lifetime (now being the second time),
so it's either arbitrary-precision, or highest-possible precision.
When I was in school, attoseconds (as) where the shortest named
second fraction. Today, it seems we should go for yoctoseconds (ys).
There is an absolute boundary, though: it seems there is no point in
going shorter than the Planck time (5.4 * 10**-44).
That is an implementation detail. Python implementations in other universes
may not have that limitation.
Besides, if any of the speed of light c, gravitational constant G, Planck's
constant h, or pi change, so will Planck time. Perhaps they should be
environment variables?
