It seems pretty clear what it thinks it's doing -- namely, defining complex(a,b) = a + ib even when a,b are complex. And half of why it does that is clear: you want complex(a)=a when a is complex. Why b should be allowed to be complex too, though, it's hard to imagine. -- g _______________________________________________ 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
