Jason, what do you think about this very old request? Implementing the warning
itself should be pretty trivial (and we could have outside -Wall and -Wextra,
thus should bother no one), but I'm not sure we really want it. Then I'm not
sure where we want to draw the line, eg, in the provided snippet I'm not 100%
sure about the base class case.
