* Make it so that recursive newtype declarations don't send GHC into an infinite loop. newtype T = MkT T This happened because Type.repType looked throught newtypes, and that never stopped! Now TcTyDecls.mkNewTyConRep does the job more carefully, and the result is cached in the TyCon itself. * Improve the handling of type signatures & pragmas. Previously a mis-placed (say) SPECIALISE instance pragmas could be silently ignored. Both these changes involved moving quite a lot of stuff between modules.
