the two dominant virtual machines - .net and the jvm both handle circular references with no problem whatever. this is standard in modern garbage collection - go read a book on the subject (personally i like grune et al's modern compiler design). it *is* a solved problem. if anything, python is behind the curve, not ahead of it, but this may change with the next generation of python implementations (pypy targets a variety of vms, i think). as for the extra methods you suggest - why do you want to expose implementation details in an api? that is not the normal aim of good design. andrew -- http://mail.python.org/mailman/listinfo/python-list
