1. toMaybeText :: [Text] -> Maybe Text

   wai-saml2	Network.Wai.SAML2.XML

   toMaybeText xs returns Nothing if xs is the empty list, or the result of concatenating xs wrapped in Just otherwise.

2. liftMaybe :: forall (b :: Type -> Type) a . Functor b => Maybe a -> Wizard b a

   wizards	System.Console.Wizard
