GHC support for the new "record" package

[Daniel Trstenjak]

Hi Konstantine,

If you're inside a record context you might just have something like:

   let bar' = bar { foo.val = 10 }

and

   let val = bar { foo.val }

or even

   let bar' = bar { foo.val %= someFunction }


This just seems to be some kind of syntactic sugar, so it's most
likely less powerful than real lenses.


Greetings,
