Allow view patterns inside record patterns
I think it would be nice if I could directly write a view pattern inside a record pattern. Currently the following program causes a parse error.
{-# LANGUAGE ViewPatterns #-}
newtype Foo = Foo{ fooA :: Int }
main = case Foo 4 of
Foo{ fooA = show -> s } -> print s
--Foo{ fooA = (show -> s) } -> print s -- This version is ok.
