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
