One for the weekend: challenge
The deck is pretty-well “stacked” in favor of LISP on this one: the nature of the problem lends itself particularly well to recursive solution and to so-called “pragmatic programming” (a LISP specialty in which programs build lists and then execute those lists).
I generally don't think that it's too useful to compare “language to language” without first giving very careful consideration to what it is that you are trying to do. Languages are tools... nothing more. You need to evaluate a great many non-computer factors when deciding what language(s) to deploy against a particular business task.
