do without messing with sys.getframe(). It reminds me a little bit of the dynamic binding in Emacs lisp. As incredibly useful as that is sometimes, it's a disgusting hack. :) And, if I understand correctly, something from which the Lisp community is moving away--preferring, instead, the notion of "lexical scoping" such as in Scheme. Well, global variables in Common Lisp are still dynamically-scoped, which makes perfect sense IMO.

Also, I think there is a SRFI almost every Scheme implements (SRFI ~ PEP) which add dynamic bindings.

Cheers, Michael
