I know well that people used to C++ will likely do this. However, one can get in

The disadvantage of this approach is that, if one forgets to add that "final",
it doesn't just produce a performance hit -- it means that it may be impossible
to correct without breaking downstream code, because users may have overridden
class methods that weren't meant to be virtual.
D doesn't allow overriding non-virtual functions (unlike C++).
