"See and despair: x<-y (assignment) is parsed differently than x < -y (comparison)!" And that guy talks about computer science? "<-" is a single token, what is so hard about that? It is a lexing issue, not a parsing issue! Surely one cannot accuse OCaml of being written by laymen: # type r = { mutable x : int };; type r = { mutable x : int; } # let y = { x=10 };; val y : r = {x = 10} # y.x <- 100;; - : unit = () # y.x < -10;; - : bool = false
