Apart from Dockins' typenats library there are no other user-friendly
specific type-level libraries that know, so I cannot really tell if
people would prefer a hold-all library or a couple of more granular
specialized ones.

Right now is not hold-all at all (it is still vaporware actually :)),
so I think there's no reason to discuss that at this point. Let's see
what people think.

Thanks I'll have a look at it.

Sure. I've actually been exchanging mail with Oleg. He has given me
some useful suggestions and contributed with some code. He didn't
mention to what point he wanted to get involved though, but I'm sure
he will try to help.
