    7777used to add non-static members" to classes. This is precisely what that example does, and the funny thing is that it compiles and runs ok. I don't see how that can work, unless the compiler is treating the templated method as final.

    8383That is incorrect.  Though I think templates can not add virtual members to classes (ie. I believe template methods are implicitly final). Though I have not tested this to be sure.

    89 Though the spec says a mixin *can* add virtual functions to a class. That said, I recently encountered a problem whereby a class method refused to override the templated version.

    9595I expanded that example a bit to use inheritance and it looks like the documentation is wrong... Not only are the functions non-static and non-final but are (correctly) virtual as well.
