Yes, that could be another point in the division of the "OO programming
concept" into smaller, more "primitive" features -- building blocks --
which could be combined in various ways.
Your suggestion would allow class-wide programming without storing tags
_in_ objects.

Indeed. However, while I insist on re-dispatch in some cases, I don't
insist on re-dispatch in all cases :-) The possible need for
re-dispatch would then be one of the reasons for choosing the untagged
approach (your suggestion) or the tagged approach (present Ada).
