[Haskell] View patterns in GHC: Request for feedback

[Dan Licata]

Hi everyone,

Simon PJ and I are implementing view patterns, a way of pattern matching
against abstract datatypes, in GHC.  Our design is described here:

http://hackage.haskell.org/trac/ghc/wiki/ViewPatterns

If you have any comments or suggestions about this design, we'd love to
hear them.  You can respond to this list (and we can take it to
haskell-cafe if the thread gets long) or, if you prefer, directly to me.

Thanks!
-Dan
