Seems like You want to solve the addressed generator problem by manipulating the syntax: "make generators look more function like", because father compiler won't complain ;-) Sorry, but IMO this is hackery and has nothing to do with good language design and I consider this as extremely harmfull. Instead of making things explicit it does it the other way round and tries to make Python code more obscure. Moreover I can't notice the superiority of thunks in Your other examples over more common techniques like decorators for pre- and postconditions and the GOF command pattern. I thinks the place for such ideas are Michael Hudsons famous bytecodehacks. -1 for from me for thunks in Python. Ciao, Kay -- http://mail.python.org/mailman/listinfo/python-list
