The above can be reduced to one line, without temporary file.
In fact, I feel more like we would need a "-silent" option, to get rid
of prompts and types (this is already the default with scripts).

echo "print_int Sys.word_size;;" | \
ocaml | grep "^# ." | sed -e "s/# //" -e "s/- :.*//"

A shorter but more specific approach is

echo "Sys.word_size;;" | ocaml | grep "# -" | sed -e "s/.*= //"
