Are type classes different from Java classes? I think so, but I guess this means that one should ask different things to type classes, respect to what is being asked to Java classes. It is this difference that's unclear to me.
I made some notes about this, but they're in no sense authoritative: http://www.ninebynine.org/Software/Learning-Haskell-Notes.html#type-class-mi... There was also a little discussion of these notes, starting around: http://www.haskell.org//pipermail/haskell/2003-December/013269.html and subsequently transferring to Haskell-cafe.
