in some cases a ways above the ones from 8.0.
But I see no changes in the tessuite in this patch. So what regressed? Or, were all the regressions relative to 8.0, and had already been accepted for 8.2? Which cases in particular regressed wrt 8.0? "Some cases" isn't very explicit! Did removing the `coreBindsSize` improve compiler speed (slightly) becuase of doing less work? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13426#comment:43 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
