I originally had field puns in GHC, and then took them out when Haskell 98
removed them, after a discussion very like
Hello,
(Malcolm, sorry for the double post, I forgot to CC the list)
I was thinking mostly about the old-time-y punning, where I can

we implicitly get
f :: T - Int
which punning shadows with
f :: Int
whereas I generally avoid shadowing completely.
I agree with Ian.
