example
 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
