I wrote a quickref to the AST node structures that also includes a description of a generic method for traversing an arbitrary AST. You can find it at http://mkremins.github.io/clojure-ast-ref. The essence of it is that the :children vector is an ordered vector of keys into the AST node. Each of these keys is guaranteed to point t -- You received this message because you are subscribed to the Google Groups "Clojure" group.
