Hey ho,

Is there any way two find out whether two variables refer to the same cell? That is I'm looking for a notion of identity (compareable to == in Java) as opposed to equality (== in Haskell).

If you haven't seen this thread already: "Detecting Cycles in Datastructures" covering exactly your topic, I think.. You can use google groups to find it. It's from okt. Marc
