Do they honestly expect me to believe that there wasn't a more appropriate way to abbreviate "cumulative maximum" than cummax? Imagine the headaches the inventor of the world's first Python powered sexbot will suffer when they realise that the method name cummin has already been taken.
fr, "cummax()"? a more sensible API designer would call it "goon()"
Go on...
☝️🤓 cummax is a distinct kink subculture!
From what little I know about the devs, I expect they already created a function called goon() as an abbreviation of something mundane like "generate one-tenth of number" and just divides a number by 10.
