[Haskell-cafe] Pattern matching with OverloadedLists

Hello Cafe, wiki for OverloadedLists says that g [x,y,z] = ... is treated as g (toList-> [x,y,z]) = Shouldn't this work? Both 'f's should be treated the same. f :: Text -> Int f (toList -> ('9':_)) = 1 -- OK f ('1':_) = 2 -- Couldn't match expected type ‘Text’ with actual type ‘[Char]’ (OverloadedStrings is also on) Am I missing something? br, vlatko
