Hi there. Could somebody please let me know where I've gone wrong in the program below (yesterday's CVS HEAD stage 3 compiler on Windows)? ------------- TH - printf.hs --- module Main where import Language.Haskell.THSyntax data Format = D | S | L String main = putStrLn ( $(pr "Hello") ) parse :: String -> [Format] parse s = [ L s ] gen :: [Format] -> Expr gen [D] = [| \n -> show n |] gen [S] = [| \s -> s |] gen [L s] = string s pr :: String -> Expr pr s = gen (parse s) ------------- Command Line ----- /c/cvs/i386-unknown-mingw32/stage3/ghc/compiler/ghc-inplace -fglasgow-exts - package haskell-src printf.hs -o printf.exe ------------- GHC output--------- printf.hs:7: Stage error: `pr' is bound at stage 1 but used at stage 0 In the first argument of `putStrLn', namely `($[splice](pr "Hello"))' In a right-hand side of function `main': putStrLn ($[splice](pr "Hello")) In the definition of `main': main = putStrLn ($[splice](pr "Hello")) ----------------------------------- Thanks Mike Thomas.
