This diagnostic is infuriating. You could easily spend the better part of an
hour trying to diagnose what's wrong - the actual issue is that `Clock` refers
to two completely different symbols.
But the compiler is not helpful - it keeps recommending to override the method
without giving a hint to what is wrong.
