Message-ID: <532DEC4E.6040505@hot.ee> (raw)
Using ocaml 4.00.1 the program below successfully compiles. I think
this should be rejected because the call (f t) forces t to be of type t2
whereas the annotation on input function requires it to be of type t1.
type t1 = T1
type t2 = T2
let f T2 = ()
let input (c : in_channel) : t1 =
let t = input_value c in
f t;
t
