Hi folks,

I was really annoyed by the fact that for Data.Map and Data.Set are no Read instances declared, but Show instances are! I believe there should be some kind of unwritten rule that in the standart lib the Show and Read instances come pairwise and are fully compatible.

I've been annoyed by this too. I wrote my own instances at one point. Frederik
