Re: [Haskell-cafe] Automatic derivation (TemplateHaskell?)

This is in Language.Haskell.TH.Syntax which is imported at the top of Data/Derive/TH.hs so I don't understand the cause of the error instance Functor Q where fmap f (Q x) = Q (fmap f x) Copying the above into TH.hs gives me Preprocessing library derive-0.1... Preprocessing executables for derive-0.1... Building derive-0.1... [4 of 9] Compiling Data.Derive.TH ( Data/Derive/TH.hs, dist/build/ Data/Derive/TH.o ) Data/Derive/TH.hs:23:10: Not in scope: data constructor `Q' Data/Derive/TH.hs:23:17: Not in scope: data constructor `Q' But Q is exported by Languave.Haskell.TH.Syntax !!! Any suggestions? Thanks, Joel -- http://wagerlabs.com/
