4404,RecordWildCards,igloo,igloo,"With this module:
{{{
{-# LANGUAGE RecordWildCards #-}

module TT where

data T = T {t1, t2 :: Int}

f :: T -> Int
f d = x
    where T {t1 = x, ..} = d

g :: T -> Int
g (T {t1 = x, ..}) = x
}}}
`f` gives warnings about t2 being unused:
{{{
$ ghc -Wall -c n.hs

n.hs:9:11: Warning: Defined but not used: `t2'
}}}
which is probably not what we want for variables bound by a wildcard. Reported by Serge here:
