[Haskell-cafe] Data.Ring -- Pre-announce

Hi List, I recently needed a ring structure (circular list with bi-directional access) and didn't see anything obvious on Hackage. I threw something together fairly quickly and would like some feedback before tossing it on Hackage. I'd really appreciate if some one would: 1. make sure the code looks goodish (127 lines with full docs) 2. make sure my tests look saneish If I hear nothing, I'll assume wild support and push to Hackage. Code: http://github.com/sw17ch/data-ring/blob/master/src/Data/Ring.hs Tests: http://github.com/sw17ch/data-ring/blob/master/tests/quickcheck.hs Package Root: http://github.com/sw17ch/data-ring Thanks ahead of time, John Van Enk
