Since I'm running NixOS:
$ nix-env -iA nixos.ocaml
$ ocaml
This book seems mostly designed to be done from the REPL for the first parts.
The default OCaml REPL is a little bare-bones (doesn't even have arrow keys), so
in Chapter 05: Sorting Things I wrote a default.nix to
bring in utop, which is a nice wrapper that makes the REPL much more usable.
