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

is perfectly plausible code.

I have my doubts. Sure, you can write it, but what would you use it for? What's your use-case?

Any varying optimal control might also be subject to bounds that vary. These problems arise rather frequently in economic theory. Often the cheapest way to compute them is to compute an unconstrained problem and clamp. I can even think of a case where clamp could be used with a constant control and a varying bound: S-s inventory control facing occasional large orders in an otherwise continuous, stationary demand process.
