* status: new => closed * resolution: => wontfix Comment: I'm going to close this. It just doesn't work to have multiple versions of a wired-in package, all kinds of things could go wrong. We currently allow multiple versions to exist, but only the latest is considered to be "the" wired-in one. This was to make it possible to have both `base-3` and `base-4` coexisting, where `base-3` depended on `base-4`. This doesn't apply in the above template-haskell example, where the two packages are really independent. I think the right fix is just to not do this, and if I understand correctly the latest version of Cabal is better at avoiding it anyway. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/5704#comment:6> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
