I would say that this proves that dicts and complexes are more general, rather than more fundamental. The fundamentals of boolean logic are AND/OR/NOT, but it's common to build everything out of the more general NAND gates because they can do everything. (I may be sketchy on details there, I'm a software guy not a hardware designer.) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
