Also it seems that templated methods in abstract class are treated as final
implicitly. But there is, at least, little bit cryptic message "non-virtual
functions cannot be abstract". So it seems the compiler applies hidden "final"
attribute an the method declaration. I think compiler should enforce explicit
"final" attribute to be declared by user on the method.
