Incorrect defined but not used warning with record wildcards
{-# LANGUAGE RecordWildCards #-}
module Test where
data T = MkT { f,g :: Int }
p1 x = let MkT{..} = x in f
p2 MkT{..} = f
With GHC 6.12.3 this gives the warning:
Test.hs:7:11: Warning: Defined but not used: `g'
i.e. p1
gives a warning, but p2
doesn't. Neither is meant to give a warning.
