Re: [Haskell-cafe] ANN: Bookkeeper

Book seems to use a quicksort (in package type-level-sets) to avoid duplicates. A couple years ago I did a benchmark http://code.haskell.org/~aavogt/HList-nodup/Run.html that includes a different quicksort. It is a good method, but maybe type-level-sets has a better implementation. Provided my timings generalize, I think dealing with many records of 50 elements will be frustrating.

This is really interesting. But how many fields in Book could be? I'm afraid there could be a problem for time and memory consumption by compiler. Isn't it?

I was playing around with GHC 8 yesterday, and ended up writing another extensible records library:

And a blog post about it:

I hope someone finds this useful!
