PLT Scheme has a construct called "shared" that makes it easy to construct self-recursive data structures without mutation. It's sort of like a "letrec" for data: http://docs.plt-scheme.org/reference/shared.html So it's definitely possible to make it easy to write self-recursive data structures in an eager functional programming language without mutation, but I'm not aware of a way to do it in Clojure. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
