[Haskell-cafe] Re: mapping unfreeze over an IntMap of IOUArrays

Hmm. So you'd need to construct a new IntMap, made by fmap'ping unsafeFreeze over each element of the old map.

I guess if we had a Traversable instance for Data.IntMap things would be just fine. Would this be a bad thing in any way? Chad
