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

[Chung-chieh Shan]

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.
