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!
