Hello,

I'm pleased to announce the release of my new library, named "has", written to aim to ease pain at inconvinience of Haskell's build-in records.

Hmm, nice work, looks interesting.

With the has, You can reuse accessors over records to write generic function, combine records with another.

Repository is at GitHub: http://github.com/nonowarn/has Uploaded on Hackage: http://hackage.haskell.org/package/has

So you can install this by "cabal install has"

You can use the has in three steps (without counting installation).

This is going out of style. It would be nice to know specifically what LANGUAGE extensions are necessary. Luke
