Hi, in the ObjC++ section, it says that "C++ classes (...) that have one or more virtual methods" can't be used as instance variables. Isn't this no longer true? This used to be a problem in the old days (e.g. MacOS X 10.2 and earlier, IIRC) when ObjC didn't call constructors on C++ instance variables, but since it does call default constructors, the vtable gets initialized correctly, so why *wouldn't* an object be permitted to have virtual member functions? Anyone have a reason why I shouldn't remove that mention or at least relativize it by "under older ObjC runtimes"? -- Uliwitness ( talk)
