Do racket macros have more advanced functionality than those found in Scheme or Common Lisp? I suspect so, especially regarding modules, namespaces and scoping, etc, but I'd appreciate a simple rundown of what Racket macros can do that other lisps can not, if anything. Additionally, Scheme/CL also expose the reader layer to the developer, and using this, is it not also possible in those lisps to create entirely new languages (not s-expr macros), such as Scribble? In other words, Is Racket simply a philosophy/convention of language oriented programming with convenient syntactic wrappers to this end, or does it more fundamentally extend Scheme to do things technically impossible in that language? Thanks a lot. -- Talk to you soon, Scott Klarenbach PointyHat Software Corp. <a href="http://www.pointyhat.ca" target="_blank">www.pointyhat.ca</a> p 604-568-4280 e <a href="mailto:scott@pointyhat.ca" target="_blank">scott@pointyhat.ca</a> #308 - 55 Water St. Vancouver, BC V6B1A1 _______________________________________ To iterate is human; to recurs, divine
