I was hoping it was going to be in the standard library, but non-core.
Using it for manipulating .pos, OTOH, would seem to make it core, which
I suppose is probably worth it.

The problem with it is that somehow we have to get 5`m / 30`s to work,
even though m is an operator, which AFAIK means it needs to be a macro,
or the moral equivalent (is parsed).
Also, having every unit be a like-named class would very much crowd the
root of the namespace.
