Yes, I'm wavering on this, too. I'm reasonably convinced that the complex constructor is wrong to accept a float return from __complex__. But it's not clear to me whether it's better to break backwards compatibility by fixing that in 3.4, or to accept the mistake and make cmath behave analogously. > Also PyComplex_AsComplex() should perhaps enforce that. It already does. `complex_new` doesn't use `PyComplex_AsCComplex`. -- Mark _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
