What to do at the module level is less obvious. Having several packages provide different implementations of the same thing is arguably useful. (E.g., I know Gtk2hs provies an SOE module. What about wxHaskell? If the interface is standard enough, a given application might not actually care which implementation it gets.) I'm open to suggestions here...
The standard way to deal with this is virtual packages. But this would require significant changes to Cabal, not only to track multiple names for a single package but also to not complain about collisions. -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH
