I've had to define an identity function from time to time. Most
recently I wanted to define a function for printing labels on charts:
let plot ?(labels = identity) data =
(* ... *)
Called as:
plot ~labels:string_of_int data
if the label was an int instead of the default string. There was a
thread on this on ocaml-beginners I think.
