[Haskell-cafe] Cabal extensions tracking

It's possible to enable extensions using an "extensions" field in a
Cabal file, in which case Cabal will be able to report what language
extensions the package requires. Unfortunately, this can be confusing,
since the extensions in effect do not appear at the top of each
affected module. Is there any way to get Cabal to report required
extensions *based on LANGUAGE pragmas*?
