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

[John Meacham]

another thing is that for any record syntax, we would want higher order
versions of the selection, setting, and updating routines. A quick
perusal of my source code shows over half my uses of record selectors
are in a higher order fashion. (which need to be generated with DrIFT
with the current syntax)

I mean something like 

map (.foo) xs
to pull all the 'foo' fields out of xs.  (using made up syntax)

or 

map (foo_s 3) xs

to set all the foo fields to 3. (using DrIFT syntax)
