Hi cafe, Is there any way to add the documentation comment for the instances defined with StandaloneDeriving? I'm currently defining data-type using GADTs and its Typeable instance. Normally, this can be done only StandaloneDeriving and DeriveDataTypeable extensions:
{-# LANGUAGE StandaloneDeriving, GADTs, DeriveDataTypeable #-} data Ordinal n where OZ :: Ordinal (S n) OS :: Ordinal n -> Ordinal (S n)
deriving instance Typeable Ordinal
I added `Typeable` instance for Ordinal recently, so I want to add some comments like "Since 0.2.3.0". But any of the following doesn't work or, even worse, haddock won't compile: * Just before `deriving instance` line using `-- | ` * Just after `deriving` keyword but before `instance` using `-- | ` * Just after the `Typeable Ordinal`, but no newline in-between, with `-- ^ ` * The next line of `deriving` clause with `-- ^ ` Is there any way to add documentation for instances with standalone deriving, or it's just not supported yet? -- Hiromi ISHII konn.jinro@gmail.com
