Are there GHC extensions we'd like to incorporate wholesale?

I wonder if there are GHC extensions we'd like to promote as features in the next report, as a starting point for discussing new additions. There are a few GHC features that have become part of the regular Haskell landscape, such that it's hard to imagine a modern Haskell without them. For example, MultiParamTypeClasses, OverloadedStrings, GADTs, TypeFamilies, etc. How much "work" is typically involved in promoting a feature to be in the Report, and how do we determine when it's a bad idea? -- John Wiegley GPG fingerprint = 4710 CF98 AF9B 327B B80F http://newartisans.com 60E1 46C4 BD1A 7AC1 4BA2
