I use a very simple way to achieve this: just tell the unix system to
execute the right ocaml interpreter, then I execute the file as
pauillac:~$ cat > essai
print_string "Hello world!"; print_newline();;
pauillac:~$ chmod a+x ./essai
Normally I use a special version of ocaml, with the regexp and unix
libraries linked, but it's the idea: just write plain caml code and
interpret it ! In many cases it is fast enough for what I need!
What do you think of this completely interpreted approach ?
