Metafunctions

[Marcus Comstedt (ACROSS) (Hail Ilpalazzo!) @ Pike (-) developers forum]

Neither of these are working solutions.  The first because the names
"add_one" and "add_two" are not statically known in the real case, but
dynamic data from the parent object.  The second becase, come on, you
can't really expect anyone who wants to override a method in a class
to write something corny like that?  I can write convoluted stuff in
Base, because it's just one class, but Sub must be convenient to
write.
