I just installed Camllight and I encountered the problem as you. Because the
type menu is just a shorter name for the complete type (string * string) list,
you have to use:
type menu == ( string * string ) list ;;
(with two '=' signs)
I don't know the exact rule about this. It might be close to the difference
between 'type' and 'data' in Haskell.
Good luck!
