Just wanted to let people know that I've been working on improving Data.HashTable, with the help of Ketil Malde's badly performing code

Always happy to help, of course - bad performance R us:-)

Request: Data.HashTable.Immutable

I'm not sure you really want that - do you wish to copy a large array each time you do an update? Freezing and thawing might be a good idea, though. HashTable's interface is rather impoverished, compared to Map and even Array. Ideally, it should support many of the same operations, and presumably it could work with the ST monad as well as IO. -k
