Attaches Haddock documentation to the declaration provided. Unlike putDoc , the names do not need to be in scope when calling this function so it can be used for quoted declarations and anything else currently being spliced. Not all declarations can have documentation attached to them. For those that can't, withDecDoc will return it unchanged without any side effects.
