@RichFelker@khaxan One of my 1y students wrote for 30-day check: x != 1 && x*x % 5 == 1. Cool but I don't want to see it in real code:-) -
@ch3root@RichFelker hahaha seems really inefficient hahaha -
@khaxan@RichFelker It's not much slower than x != 2 && x % 7 % 2 == 0. What concerns me is that it's completely non-evident.
