module simple_example

-- a basic top-level function:
let add2 x = x + 2

let something_with_let_bindings x =
  -- a function:
  let adder a b = a + b in
  -- a variable (immutable):
  let x_plus_2 = adder x 2 in
  add2 x

-- a polymorphic ADT:
type messages 'x = 'x | Fetch pid 'x

{- A function that can be spawned to receive `messages int`
    messages, that increments its state by received integers
    and can be queried for its state.
-}
let will_be_a_process x = receive with
    i -> will_be_a_process (x + i)
  | Fetch sender ->
    let sent = send x sender in
    will_be_a_process x

let start_a_process init = spawn will_be_a_process init
