@Dan

is it still 3X?

Yes, extrema() is still 3x slower

@rafael.guerra

range4b() is ~5% faster

branch prediction?

@DNF

Can you take a look at Base.extrema and see if you can tell what, if anything, is wrong with it, performance-wise?

One answer is #45581. Which seems to be 3-4x faster than the functions above.

Thank you for all the valuable answers. In the absence of a dedicated range function in the standard library, I marked the one from @stillyslalom as the solution, as it is the most compact one that uses extrema(), which according to @mcabbott will be greatly accelerated soon.
