Even with functionalists ---of the OCaml and SML ilk--- this use of spaces can be confusing if noone explains that function application binds tighter than all operators.
Bwuh? Ocaml programmers certainly know that application binds tighter than operators. And as:
let f x y = ... in f a b
is more efficient (in Ocaml) than:
let f (x, y) = ... in f (a, b)
(Ocaml doesn't optimize away the tuple allocation)...
That is incorrect. OCaml does optimize away that tuple: both forms compile to the same 2-argument function. OCaml does not optimize away this tuple: let a, b = 1, 2 So, when efficiency is important, you write: let a = 1 and b = 2 -- Dr Jon Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?e
