Hello, I had this example that was working with earliest versions of GHC but it doesn't work with GHC-6.6. $(deriveReflectable ''[]) Above this isn't a double quote but two single quotes. It may not be clear with some fonts. Is this a bug or just there is a change in the syntax? The error that I get is: src/Database/HarmonyDB/Instances.hs:1:0: Illegal variable name: `[]' When splicing generated code into the program Regards, Krasimir
