The Standard Haskell committee is debating a possible modification to
the semantics of pattern matching; the goal is to make the language
simpler, but the cost is an incompatible change to a basic part of the
semantics. To help us weigh up the cost against the benefit, we'd like
to poll the opinions of Haskell users.
You can read about the issue at
http://www.cs.chalmers.se/~rjmh/Haskell/Messages/Polls/matching.html
where you'll find a link to a web form for collecting votes.
Please give us your views!
