Re: Who needs Ord for Sets and Maps anyway?

G'day all. Quoting Sebastian Sylvan :

A good "standard" class hierarchy for collections and several implementations is very much needed, IMO.

For the record, the consensus seemed to be that we needed something, but Edison wasn't it. One problem that I got bogged down in was the idea that some data structures most sensibly reside in monads (e.g. IOArrays) and some do not. A consistent interface for both proved elusive.
