The fn that does the display is the one having side effects. Now if your look fn creates the side effect, it should reflect that in its name.
But... I wonder why it does so. Looking at something does not change state. You may be better splitting the side effect away from it or change the name. Looks (no pun intended) odd from a naming perspective but w/o looking at your code base it's hard to telll. It may made sense in your context. If look is a predicate, the name might not be appropriate. number? is clearly a predicate. "look" does "look" as a true/false property to me. visible? or hidden? look to me as a predicates. But again it may make sense in your context. If your fn does too many things, you may want to split it.
