Maybe I'm off track here, but this resounds to me as similar to the arguments that I listened to in lecture 2a of the SICP course. In that lecture, they introduce the representation and manipulation of pictures. They introduce a single primitive and then build on top of that. They create a dsl specific to pictures processing that is "embedded" into lisp. So it inherits from lisp the common means of expression (abstraction, combination, recursion and whatnot) I see a sort of kinship, here, between DOM elements and SICP pictures. In fact, they stress that "data" representing pictures are the same kind of lisp citizens we already knew. Data are blurred with the language, in lisp. In the DOM case macros are necessary because there's the html to deal with. So I guess that the solution is to use the macros to end up with lisp stuff and then work with that, rather than the other way around. I hope I didn't make myself a fool, here -- You received this message because you are subscribed to the Google Groups "Clojure" group.
