Re: ANNOUNCE: attribute 0.1

G'day all. Quoting Ross Paterson :

For an alternative design, see

The problem with this design is that there may, in general, be more than one "interesting" kind of Ref on a given state monad. For example, I often use my own IORef-like class which supports the Ord interface. Others might want IORef-like objects which support Hashable, or Show. Cheers, Andrew Bromage
