I think they (and (,,,)) should be left unqualified.

I've noticed a wierd GHC behaviour (version 6.6 sorry) when using the
constructor qualified. Is there a reason for which GHC fails parsing the
following declarations?

You aren't allowed to qualify [], -> or (,,,) according to the Haskell 98
report.
