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. :-(
RWH is free and online, and covers many useful things. There's no excuse :-)
Knowing about something /= knowing how to use it. I own and have read RWH, but I've never had to use hsc2hs, or Applicative, etc.
Writing libraries that bind to C is a great way to have to use a lot of hsc2hs (or c2hs), so clearly you need to contribute more libraries :-) But in this case, the OP didn't even know *about* the something. -- Don
