But I wonder if the compiler picking a common ancestor from a complex inheritance graph is really a good thing - it may prove surprising to the user. For example: interface A : B,C,D,E interface X : M,N,O,C Is it really the right idea to pick C for the common type? I'm skeptical. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
