This list _is_ for mature extensions to the language, to be considered for embedding into the formal standard [as I've been told several times].

There have been many, many critiques of Haskell's current record system; and many, many proposals -- this is exactly what's blocking progress. I'm not sure you've fully characterised all the current difficulties. (For example: what is to be the principal type for your anonymous records? Are two records with the same-named fields, and at the same types, but in a different l-to-r sequence to be treated as 'equivalent'?) I don't see you comparing your suggestion to others. (As Christopher noted, it does at first sight look like TRex. Do you understand why TRex was abandoned?) There's a substantial body of recent debate and suggestions at http://ghc.haskell.org/trac/ghc/wiki/Records . This [Northern] Summer's GSoC project on OverloadedRecordFields that Wvv ref'd is just one point in the possible design space. You can trace backwards from those wiki pages to many threads of discussion. _______________________________________________ Haskell-prime mailing list Haskell-prime@haskell.org http://www.haskell.org/mailman/listinfo/haskell-prime
