| So, DoCon remains with ghc-6.8.2 -- untill GHC fixes the problem. | | Hm ... a small module needs > 600 Mb instead of 80 Mb to compile, | and the release is considered as a progress. | All right, this may occur correct -- if the developers know what | namely must be fixed, and also know how to fix it. If so, then I could | believe. I have looked into this a bit. It's because GHC currently inlines every instance declaration bodily, code and all. DoCon has a lot of instance declarations with a lot of code in them, so there's a tremendous amount of code duplication as a result of dictionary construction. I've been working on a fix for this -- it bites every program, but DoCon especially -- but I have not yet managed to complete it. I'm not quite sure why 6.8.3 is worse than 6.8.2, but both are bad. I'm hoping for a dramatic improvement once I've done my fix. Simon
