If a comparer isn't provided, it was silently assuming the element type implements Comparable, even though that isn't required. Fixed to add a manual cast at each comparison. A stricter faster approach might be to check that the type argument itself is a type that implements Comparable, but I don't know if that's too pessimistic, or even possible to do.
