Point of clarification for readers who aren’t familiar with Haskell: Haskell doesn’t have operators in the classic sense, since they’re just an alternate syntax (infix) for regular functions; implemented in libraries. The Haskell ecosystem OTOH has a shitton of infix functions, as does Edward Kmett’s lens library. I don’t think there’s any reason to bother memorizing the ones that aren’t useful to you. You can always search them on Hoogle if you encounter one you don’t know. E.g. https://hoogle.haskell.org/?hoogle=%28%5E.%29&scope=set%3Astackage https://hoogle.haskell.org/?hoogle=%28%5E.%29&scope=set%3Ast... I use lenses frequently in a large application and have only ever used view, set, and over.
