[Python-ideas] Consider adding clip or clamp function to math

[David Mertz]

FWIW. I first opined that people should just write their own utility
function. However, there are enough differences of opinion about the right
semantics that I support it being in the standard library now.

Those decisions may or may not be made the way I most prefer, but I think
an "official behavior in the edge cases is best to have... I can always
implement my own version with different behavior if I need to.
