OK, then how would you replace SCM_VECTORP and friends?  How does your
virtual function lookup mechanism look when using goops?  I'm curious,
because I currently don't see how low-level types can be virtualized using
goops without a noticeable performance drawback.  Could you give a code
example for how you would do it, please?
