How to get "opam init --comp=..." to install at the latest OCaml version?

If there is no version of OCaml already installed on the computer, running opam init will ask you to specify a version of OCaml to install by default. That's great.

Is there a way to ask it to install the latest released version? It would make scripting the installation easier than having to look up what is the latest version each time.

Well I got no answers so I came up with the following:

latest=$(
    curl -s "https://opam.ocaml.org/urls.txt"                            | \
        sed -n -e '/^compilers/ s/^compilers\/\([0-9.]*\)\/\1\/.*$/\1/p' | \
        sort -rn | head -n1)

opam init --comp="${latest}"

Seems to work.
