This works out nicely, but only because I know which of the
overloaded functions is the "master" master function. In
general I wouldn't know that (unless it's documented), so I'd
be forced to override all of them. The burden would only get
worse as the inheritance hierarchy deepens. Moreover, such
dependency could arise could arise with non-overloaded member
functions as well.

Other than relying on documentation, is there an idiomatic way
of marking the "master" function, so that others writing
derived classes knows which to override?

The usual solution is that only the actual "master" function
will be virtual. In fact, more usually, it will have a
different name, and very often will be private.
