OCaml: Warning S: this expression should have type unit

Question

Code

Stack.pop some_stack;

generates "Warning S: this expression should have type unit.". Is it possible to mute it without assigning result to some variable?

Thank you.

Answer 1

You can use the the argument "-w -S" to ocamlc/ocamlopt to disable this warning. See the OCaml manual here and here.

Answer 2

Call the ignore function with the result of the Stack.pop.

ignore (Stack.pop some_stack);
