[Haskell-cafe] Whither memo and hash-consing?

Hello, What is the current status of the Memo module, for memoizing functions? It seems to have disappeared from the standard Hugs/GHC distributions; are we supposed to just find the old code on Google which uses System.Mem.Weak? A related question is whether anyone has built a library for hash-consing. Ideally it's just a function "hashCons" with a type like "(Ord a) => a -> a". Thank you. -- Edit this signature at http://www.digitas.harvard.edu/cgi-bin/ken/sig The old name for the Giraffe was Cameleopard, literally a Camel-Leopard.
