I wonder if anyone can teach me properly outputing values of
following type:

type sexp =
  | Slist of (string * lsexp)
  | Satts of lsexp
  | Sbody of lsexp
  | Sattr of (string * string)
  | Sdata of string
and lsexp = sexp list.

Even default(and hence dumb) interactive ocaml toplevel printer does
it better than my own attempts of abusing Format.

let rec print_sexp pff = function
  | Slist (n, l) -> fprintf pff "@ @,@[<1>(%s %a)@]" n print_lsexp l
  | Sbody b -> print_lsexp pff b
  | Satts a -> fprintf pff "@[(%a)@]" print_lsexp a
  | Sattr (n, a) -> fprintf pff "@[%s: \"%s\"@ @]" n (attr_value a)
  | Sdata s -> fprintf pff "@ \"%s\"" (String.escaped s)
and print_lsexp pff l = List.iter (print_sexp pff) l
 
I must confess though, i do not fully understand what im doing here.
So please anyone.

P.S. Oh btw. this is NOT an assignment ;)
