... but not for this translation! Consider
# 4; 3;;
Characters 0-1:
4; 3;;
^
Warning 10: this expression should have type unit.
- : int = 3
By your translation, you'd have:
# let () = 4 in
3;;
Characters 9-10:
let () = 4 in
^
Error: This expression has type int but an expression was expected of type
unit
