Wrong error message when using `..' with a record update
Using `..' inside of a record update should report that it's an error to do so, but instead reports that it's an empty update. Consider this module:
{{{ # LANGUAGE RecordWildCards #
module Test where
data Foo = Foo { x :: Int }
test :: Foo -> Foo test foo = foo { .. } }}}
When loaded, it complains about the empty record update of foo
, instead of complaining about `..' being used during an update.
