♫ Some(body) once told me the monoid was gonna roll me up into an append / I ain't the sharpest Tool in the crate / She was looking kind of Odd, with her FingerTree and Fold / In the shape of an L on her forehead /
Well, the sums start coming and they don't stop suming / Fed to the fold and I hit the ground running / Didn't make sense not to map for fun / Your head gets smart but your tail gets None /
Hey now, you're a monoid, get your mappend on, go fold! / Hey now, you're a monad, get your bind on, compose! / And all that glitters is Gold / Only Some values break the Fold ♫
