[Haskell-cafe] Record updates

[Hugo Pacheco]

There is a page for extensible records in the wiki:

http://www.haskell.org/haskellwiki/Extensible_record

Haskell's records system has many insuficiencies.
Some libraries (see grapefruit or HaskellDB) encode records as
classes, but although some proposals Haskell still lacks a good
implementation for extensible and updatable records.
