@leah today I was marvelling at ocaml using @ for list concatenation, while @@ is for (low precedence) function application.

@sanityinc but @@ was added 20 years later.

@leah when was its counterpart, |>, added relative to that? It's upsetting that they're not symmetrical

@sanityinc At the same time, but I don't think <| is a better name, hrm.
