But I didn't find a natural way to do it. For example : (setq trees '((pine . cones) (pine . acorns) (oak . acorns) (maple . seeds))) ==> ((pine . cones) (pine . acorns) (oak . acorns) (maple . seeds)) (assoc 'pine trees) ==> (pine . cones) What I'd like is something that returns each value associated with 'pine. Any thought ? Thank you, Norbert
