This is already possible in the current version of Objective Caml.

        Objective Caml version 3.00

# let x = ref 2;;
val x : int ref = {contents=2}
# x.contents;;
- : int = 2
# x.contents <- 1;;
- : unit = ()

If you don't like operators ! and :=, just don't use them, and use the
regular filed acces instead!
