User are clearly told in various places that names with leading and trailing double underscores are *special*, and at least by implication they are not to be used without a good understanding of what they are. You certainly shouldn't have found any docs telling you to use __builtins__ that way. http://www.google.ca/search?q=site%3Apython.org+__builtin__ is a pretty quick way of finding the above docs, and while doing the same search with __builtins__ admittedly finds lots of mailing list archives where people have the same misconception as you did, it doesn't take one past the second page of results before you'll be right back at a post by Fredrik pointing out the same mistake. :-) -Peter -- http://mail.python.org/mailman/listinfo/python-list
