Could you explain this bit, Lie? I'm very interested. I use multiple-value result myself, for it's so practicle in given cases. But it makes me uneasy; also have the impression (why?) it reveals wrong design. About the same feeling as when I need a function both to have an effect (eg assignment outside the func scope) and return a value. I call this "action vs question" ; it more or less matches Bertrand Meyer's "Command-Query Separation Principle" (Eiffel) & Pascal "procedure vs function". In the latter case I'm 99% sure the design smells but sometines I cannot find proper code reorganisation.
