build failures when hiding non-visible imports

Hello, One of the issues I've noticed with ghc-7.6 is that a number of packages fail due to problematic import statements. For example, any module which uses

import Prelude hiding (catch)

now fails to build with the error Module `Prelude' does not export `catch' Of course fixing this example is relatively straightforward, but that isn't always the case. Would it be reasonable to change ghc's behavior to treat this as a warning instead of an error? Cheers, John L.
