Inside the foldRight1Err suite, let ~onError () = 42 in is introduced but the subsequent calls still pass an explicit {~onError = fn _ => 42}. This makes the local ~onError binding unused and duplicates the same handler literal. Either remove the local ~onError binding, or use it in the foldRight1Err calls for consistency.

Suggested change

	(Stream.foldRight1Err {~onError = fn _ => 42}
	(fn (x : Int) y => x + y) (Stream.fromList [1, 2, 3, 4]))
	10);
	testCase "empty" (fn _ =>
	assertEq
	(Stream.foldRight1Err {~onError = fn _ => 42}
	(Stream.foldRight1Err {~onError}
	(fn (x : Int) y => x + y) (Stream.fromList [1, 2, 3, 4]))
	10);
	testCase "empty" (fn _ =>
	assertEq
