Use let-binding with functions whose last argument is a closure

letfun

letfun is a tiny library which allows you to use a let-binding style to handle functions applications that expects their last argument to be a closure. It uses for this the let& operator.

For example:

let print_hello_world file =
  Out_channel.with_open_text file (fun oc ->
    Out_channel.output_string oc "Hello, ";
    Out_channel.output_string oc "World\n")

Can be rewritten as:

let print_hello_world file =
  let open Letfun in
  let& oc = Out_channel.with_open_text file in
  Out_channel.output_string oc "Hello, ";
  Out_channel.output_string oc "World\n"
