I'm not sure precisely what you mean by "temporary object", so I am taking it to mean an object that is referenced only by the VM stack (or something equivalent for other implementations). In that case: no, you can't. Take "f() is g()", where the code objects of f and g are supplied at runtime. Are the objects returned by either of those expressions "temporary"? Without being able to do static analysis of the code of f and g, there is no way to know. -- http://mail.python.org/mailman/listinfo/python-list
