(* Check that types are not uselessly unfolded *) (* Check here that P returns something of type "option L" and not "option (list nat)" *) Definition L := list nat. Definition P (e:option L) := match e with | None => None | Some cl => Some cl end. Print P. (* Check that the heuristic to solve constraints is not artificially dependent on the presence of a let-in, and in particular that the second [_] below is not inferred to be n, as if obtained by first-order unification with [T n] of the conclusion [T _] of the type of the first [_]. *) (* Note: exact numbers of evars are not important... *) Inductive T (n:nat) := A : T n. Check fun n (y:=A n:T n) => _ _ : T n. Check fun n => _ _ : T n.
