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
