I'm pretty happy with the yapps-based reader:

Well... speaking of performance, I'm not happy with the yapps scanner;
it calls the regex engine N times per token, rather than just once.

And it only parses... it doesn't flatten. (I consider that
a feature, not a bug, btw.)

Yup; a big part of the motivation for developing rdfn3.g was
to specify how N3 relates to, say, KIF, without involving
alll the hairy cwm bits.
