Hi, I have read Graham's "On Lisp". That, and my background in Java and Haskell programming were the main reasons I was drawn to Clojure. Based on that article and others like it I had the impression that program transformations like the one I suggested were relatively easy in homoiconic languages like Clojure and macros seem to be the tool to do it.
I guess what I'm really looking for now is the "how". Mark. On May 12, 1:54 pm, Sean Devlin <francoisdev...@gmail.com> wrote: > Macros are definitely the tool to do this.
