Here's a strange test case, i was bitten by it recently in a real code:
<mox.ml>
let y o =
o#moo;
1
let x (o:(<moo : string -> unit>)) =
y o
let _ =
print_int (x (object method moo s = print_endline s end));
print_newline ()
</mox.ml>
# ocaml -warn-error A mox.ml
1
In my case method moo was actually a method that locked a mutex, the
implications were quite severe.
