Did you know that you can enforce a type-variable as being "phantom" using constraints by requiring BOTH `Contravariant` AND `Functor` instances? If you can prove those constraints, you can use `phantom` to map either way! #HaskellTIL #HaskellTips
Had to subtract an offset from ALL nested Ints inside `[(Int, Int), [(Int, Int)])]` and on another occasion just `[(Int, Int)]`; so what do you do? BIPLATE! Lenses make you feel like a programming wizard. 🧙♂️ #HaskellTips #HaskellTIL #LensFriends

I've been experimenting with nested do-notation lately, mostly in tests. Helps provide logical test 'units' which help readability, and introduce new lexical scope so I don't have to think up 20 names for 'user'. Whaddya think? #HaskellTips #HaskellTIL
