You can always use the ability of Ocaml to create new operators to
partially overcome this problem:

# let ($<) s i = String.sub s 0 i;;
val ( $< ) : string -> int -> string = <fun>

# let ($>) s i = String.sub s (String.length s - i) i;;
val ( $> ) : string -> int -> string = <fun>

# "hello, world" $< 5 $> 3;;
- : string = "llo"

# "hello, world" $> 5 $< 3;;
- : string = "wor"
