I don't think so.  Polymorphism wouldn't happen for private methods by
the new look-up scheme, so that we need less care for method name
conflict.  We have to care only for methods tried to share same name
in the same class/module.

I am not sure what you meant.  Do you want private AND overridable
methods?  I am vaguely thinking of changing protected for that
purpose (or introducing a new visibility).
