It might be simpler to have Control/Applicative.hs import GHC.Conc and define the instance.
The {-# SOURCE #-} import of Control.Applicative and the accompanying boot file are indeed unfortunate. However, I like having the Functor, Applicative and Monad instances in one place. But I can easily be convinced if more people like it your way.
Might as well define an Alternative instance too.
Good point, I will try adding them to the existing patches.
It would also make sense to move the MonadPlus instance from Control.Monad.STM (where it is an orphan) to GHC.Conc.
I created a separate ticket for this (including patches): http://hackage.haskell.org/trac/ghc/ticket/4077 But lets keep the discussion about that on this thread.
Discussion period: a few days, since I think this is hardly controversial.
I think proposals should get at least a couple of weeks, even if they're straightforward.
Ok, let's set the period on 2 weeks. If this proposal does proves to be controversial I will extend the period lateron. Thanks for your comments and suggestions! Bas
