Question about variables in module behavior

tsnobip:

module MyModule = struct
  let state = ref([])

  let make (foo: string)  = 
    state := foo :: !state;
    state
end

let a1 = MyModule.make "a";;
let a2 = MyModule.make "b";;
Printf.printf "a1 = a2 ? %b" (!a1 = !a2);;

Yikes, I must have done something weird to get the results I did – I’m a complete amateur when it comes to the language. Thanks for pointing that out!
