Exactly. By and large, I think in the fire of the debate too many people
in this thread have forgotten to apply a simple OO design principle:
push policy up and implementation down. Any good primitive pushed up the
exception hierarchy is a huge win, and any design that advocates
reliance on concrete types is admitting defeat.

That because you can't (shouldn't) push up implementations specific to a
given subclass. Why don't we only have one class, Object, and add a
Variant[string] there.
Do you see how stupid that is.
