> Topics: Programming with mutable state; the State monad; using multiple monads together
-> Here are some OCaml libraries: [[Juli8|code/juli8.ml]] and [[Monad|code/monad.ml]]. We'll write up explanations of these soon.
+> Here are some OCaml libraries: [[Juli8|code/juli8.ml]] and [[Monad|code/monad.ml]]. We'll write up explanations of these soon. But quickly, before you `#use "juli8.ml"`, you have to run this in your OCaml session. (I have these lines in my `~/.ocamlinit` file, so they run every time OCaml starts up:
+
+> #load "str.cma";;
+> module Std = struct
+> include Pervasives
+> module List = List
+> module Random = Random
+> module String = String
+> end

We've added a [[Monad Library]] for OCaml.
