I'm not quite sure what ?!ng means by "the bindings of variable names are always preserved", but I conjecture that he is thinking of the "hygienic macros" in Scheme rather than the macros in Common Lisp which permit arbitrary code transformations. -- g _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
