I checked in a Read instance for Data.Set a few weeks ago, when I
needed one. An addition like this is rather obvious, so I doubt it
needs any discussion. For other changes (like Set.intersection),
some discussion might be desirable, but the best proposal is an
implemented one, which others can then improve.
Btw, I didn't add a Read instance for Data.Map.

As it should not be. It is compiler-specific. The hierarchical
libraries are supposed to be portable.
