Ok, after rereading what I posted, looks like I might not have answered the right post. So let me start over: This thread is about adding methods to a class without having it in the main class { } body, which is visible to all users. I support that idea. However, that must be entirely restricted to non-virtual methods. Adding a virtual method, like everyone who has done any binary compatibility work knows, is not possible. That includes overrides. Any and all virtual methods present in a given class -- whether new or overrides -- must be declared in the class body and visible to all users. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358 -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
