I agree that the "thrush macro" is not such a good example to show the greatness of the Lisp family of language. IMHO it's a nice syntactic sugar but it doesn't bring something fundamentally new. Still IMHO, a more suited example of the power of the macros would be how to write a memoize macro that enables to cache the results of some function.
