I have patches that main compatibility with 6.10, but now that haskell-src-meta depends of th-lift, which requires template-haskell>=2.4, I think it's a lost cause. Versioning for template-haskell makes things a real mess now---if I want a package using haskell-src-meta to work on both 6.10 and 6.12, I basically have to test the version of GHC being used and set package dependencies appropriately. Unless someone has a better way? Geoff _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
