Friends<br>
<br>
Just a heads-up. Pedro is working on implementing "Generic Defaults", as described in his Haskell Symposium 2010 paper <a href="http://www.dreixel.net/research/pdf/gdmh_nocolor.pdf" target="_blank">www.dreixel.net/research/pdf/gdmh_nocolor.pdf</a><br>
<br>
It will replace (and improve on) the "Derivable type classes" stuff in GHC at the moment, which was originally presented in a paper of that title that Ralf and I wrote in the 2000 Haskell workshop <a href="http://research.microsoft.com/en-us/um/people/simonpj/papers/derive.htm" target="_blank">http://research.microsoft.com/en-us/um/people/simonpj/papers/derive.htm</a>.<br>
<br>
The "Derivable type class" extension is barely used, I believe, and isn't even documented in the manual.</blockquote><div><br>Isn't it this?: <a href="http://www.haskell.org/ghc/docs/latest/html/users_guide/generic-classes.html">http://www.haskell.org/ghc/docs/latest/html/users_guide/generic-classes.html</a><br>
<br>But anyway, I can't remember seeing any use of it.<br><br><br>Cheers,<br>Pedro<br></div></div>
