PROPOSAL: Include record puns in Haskell 2011

[Iavor Diatchki]

Hello,
I'd like to propose that we add record punning to Haskell 2011.  I
think that this is a useful feature which makes working with record
fields easier, and reduces clutter in definitions, both in patterns
and expressions.  Furthermore, this features has been implemented in
GHC for a long time (it used to be in Hugs too, once) and we've had
plenty of time to iron out dark corners in the design.

Thoughts, objections, suggestions?
