Wow, [XML in Lisp>http://radio.weblogs.com/0102385/2004/10/04.html#a685], how awesome is that language? I mean really - it's not like they had to invent a whole new language to do it. This reminds me of the kinds of things they expect to be able to do with perl6 - but why wait? grab lisp today and you too can meta meta program.
