I don't speak Perl and didn't make it through the whole post. Is the core problem, when you strip away the app. specific stuff, that you want a hash of hashes? That's straightforward to implement:
(define top (make-hash)) (hash-set! top 'foo (make-hash)) and so on... Alternatively you can make your keys tuples: (hash-set! top '(foo bar) 'a-value) N. _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
