ppx_deferversion

Go-like `[%defer later]; now` syntax.

This is an OCaml language extension implementing a somewhat Go-ish [%defer expr1]; expr2 which will defer the evaluation of expr1 until after expr2. expr1 will still be evaluated if expr2 raises an exception.

If you are using Lwt you can use [%defer.lwt expr1]; expr2.

Thanks to Drup for guidance in figuring out ppx details!

Using ppx_defer

let () =
  let ic = open_in_bin "some_file" in
  [%defer close_in ic];
  let length = in_channel_length ic in
  let bytes = really_input_string ic length in
  print_endline bytes

See the examples/ directory for more examples.
