You might be right: on further thought, I think I want deep copies, not shallow. Originally I thought that deep copies was an YAGNI. Have you *ever* seen anyone complain that * didn't make a deep copy of the list contents? I never have. But then I realised that if this works, people will surely try to use it to make three-dimensional lists as well as two, and for that we need deep copies. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
