What if your mutatable callable object computed factorials?

Actually, my “don’t” was a response to this, as in “don’t even go there it is beyond cursed”

How about to simplify the factorial function name?

And then again it is debatable whether !(5) is truly more readable than factorial(5), especially in a language where ! usually means boolean negation
