Hello, thank you for the references. Looks promising. I will read it carefully.
A nice solution I really like was found by Alastair Reid. He proposed to me (hope it is ok to cite this) the declaration: data Salutation = [Either Char Name] We think it will not scale well, too, however, it is elegant due to its simplicity.
