This ticket serves to track the progress of the integration of core plugins in GHC (see http://www.haskell.org/pipermail/glasgow-haskell-users/2010-January/018294.html). If you are interested in having Max Bolingbroke's work merged into the mainline, please add yourself to the CC list of this ticket, preferably also commenting saying why you want plugins. This wiki page describes the design: [NewPlugins](new-plugins)
