In particular, I got rid of ic_sys_vars altogether. Mostly they can just go in ic_tythings, apart from dfuns, which are readily gettable from the instances anyway. See documentation in Note [Initialising the type environment for GHCi] in TcEnv. }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8540#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
