Bug description

I think the perl interpreter has a -e switch which allows to create
one liners in Perl.
I'd be quite happy if my interpreter of choice (ocaml) would allow
such option, in order to encourage me to put more ocaml one liners
in my bash scripts, when I am forced to do some bash scripting. :)
'-e' stands for evaluate, I guess.

The '-open' flag makes a lot of sense in this context as well.

Note that

echo 'Printf.printf "hello\n"' | ocaml -stdin

is a fairly reasonable workaround.

camlp4 has a "-str " option for the same purpose, which is indeed fairly useful.

The patch is not good enough (for example it creates a temporary file but never deletes it, littering the user's filesystem with useless source files), but in 5232 I never got feedback from the original contributor.

I'm closing this issue as a duplicate of 5232, which has the better command-line name (-str rather than -e).
