Deprecate clamp soon?

rust-lang/rust#58710 was just merged into master. This may be cause to deprecate the num::clamp function in the near future.

Ord::clamp won't be stable until rust-lang/rust#44095 closes and reaches a release. Even then, I don't see the harm in keeping num's function around. num-traits supports pretty old compilers, and it would be annoying to get a deprecation message there that you can't act on yet.

Plus there's support for PartialOrd, however questionable that may be. You've implemented clamp on f32 and f64, but that won't help newtype floats, for instance.

Yeah that's reasonable. My only reason for thinking we should maybe deprecate this is that std's clamp will account for 99% of use cases, and it's nice to unify code "look". Though tbh since this function is unopinionated about the input or output type it's completely harmless to keep around.
