I was just thinking, it might be useful to have a way of specifying
range limits to quantities. For instance, degrees Celsius don't make
much sense below -273. Degrees Kelvin are never negative. Speed can't go
beyond C (unless we're programming a StarTrek game, but then we could
have a Warp unit). Tensile strength is never negative, and so on.

Just the ability to set limits would be good to have, though; NOT the
limits themselves.

And they would only be checked by default when initializing from
constants. Run-time verifications should be explicit only, as the values
can go beyond limits when computing temporaries in long expressions.
