#9388: Narrow the scope of the notorious "state hack" -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by nomeata): I’m considering giving this one shot (pun intended), and I’m reading the current implementation of the state hack, and found some pretty old-dated comments, including this one from 2004 in `Id.hs`: {{{ -- Another good example is in fill_in in PrelPack.lhs. We should be able to -- spot that fill_in has arity 2 (and when Keith is done, we will) but we can't yet. }}} I do not know who Keith is, and why that would help, and most likely something about todays demand analyzer should be written there. Simon, if you have a minute, would you mind revisiting the comment at `isStateHack`? It would help whoever tackles the problem next. Thanks! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9388#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
