Good. However, with GHC 7.8, the following error | occurs: | | % ghci Printf.hs | [1 of 1] Compiling Printf ( Printf.hs, interpreted ) | Ok, modules loaded: Printf. | > :set -XTemplateHaskell | > putStrLn ( $(pr "Hello") ) | unknown package: main | | Is this a bug of Template Haskell of GHC 7.8? | | --Kazu
