I've never been big on the idea of duck-typing addition. Who would have thought that (1,2,3)+(4.5.6) was something other than the vector sum? I think itertools.chain more directly expresses what the OP was trying to do, and is preferable for readability, independently of these performance questions. -- http://mail.python.org/mailman/listinfo/python-list
