[Haskell-cafe] Quasi quotation question

Hello, Is it possible for a quasi quoter to have access to information about haskell identifiers declared before the quasi-quotation? I tried the 'reify' function but without success. Just as in the following exemple: a = 6 x = [$expr|a|] Where the generated haskell code is a= 6 x = a Thank you Regards J-C
