I don't think it'd be a good idea. Reason: What should be the default value of "as_element_of"? Should it be the parent of "a"? But then, you immediately have the same problem as we have now, which is the surprising (to some) fact that (3/1).is_prime() returns False. And the work-around (3/1).is_prime(as_element_of=ZZ) would be more verbous than ZZ(3/1).is_prime() Best regards, Simon -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
