Non-empty sequence http://www.github.com/massysett/non-empty-sequence
This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
I don’t maintain this anymore. I suggest you look at the nonempty-containers package. It does everything this package does, but more and better.
