[Haskell-cafe] Records (was Re: [Haskell] Improvements to GHC)

[Keean Schupke]

You can change the project and update operators in the HList library to 
behave
in exactly this way. At the moment they are constrained to not allow 
multiple
identical labels in records. If this kind of access is considered 
useful, I can
add it to the HList distribution.
