Hmm, interesting. Applicative and Traversable are two classes I've never 
used and don't really understand the purpose of. I have no idea what 
hsc2hs is. I keep hearing finger trees mentioned, but only in connection 
to papers that I can't access. So I guess that means that I don't count 
as a "knowledgable" Haskell programmer. :-(

On the other hand, I could talk for hours about stream fusion or STM. 
(Hell, I've even had a go at implementing both of these; the latter made 
it into The Monad Reader.) All of which conclusively demonstrates...
