Yes, that's what I was going to do. But, for example, I have a parse method to create such object from a string. So I need to call this method to actually create the object. Now I must put the code of the parse method into the @classmethod constructor. What if I need the parse method to be called in other parts of the program? -- http://mail.python.org/mailman/listinfo/python-list
