If it has to be static then name => index has to be global across all classes
as ISA tree adds leaves and reconverges.

Op could have a static name and lookup in a hash ;-)

See my earlier summary - static index is possible if mapping is global,
then vtable is sparse.

Good point - worth remembering when we get to op-tree structure ...
