Support for different help messages for same argument in different constructors

[GregorySchwartz]

I don't know if it's possible, but something like:

data Example1 =
  Example1
    { foo :: Int    <?> "Documentation for the foo flag in Example1"
    , bar :: Double <?> "Documentation for the bar flag in Example1"
    }
  | Example2
    { foo :: Int    <?> "Documentation for the foo flag in Example2"
    , bar :: Double <?> "Documentation for the bar flag in Example2"
    }

    deriving (Generic, Show)

Probably requiring some type of record fields. This feature would be quite useful in that you could have a program with multiple entry points with the same arguments, such as input but take in different formats.

@GregorySchwartz: I don't think it's possible, mainly due to a Haskell restriction requiring fields of the same name to have the same type for different constructors and the help text is part of the field type
