For some reason this one feels right to express with if-not to me too. The one place I’ll often use unless is things like: return unless valid raise unless h.key?(k) I think it might have something to do with: 1. How abundantly clear it is that the condition is a Boolean; and 2. The “false” condition indicating a “no work to do” situation. I think I only use them for postfix return, break, next, and raise.
