This is pretty nasty, especially since #:re-export gives no indication of
not working, and I did not, in fact, notice that it does not. I extended
equal? with a generic and it seemed to work as expected when I used
#:re-export. Was this simply a coincidence, or is equal? generic anyway?

As soon GOOPS is loaded, equal? is changed to a
"primitive-generic". IMHO, it would be nice if that would happen for
every procedure...

guile> equal?
#<primitive-procedure equal?>
guile> (use-modules (oop goops))
guile> equal?
#<primitive-generic equal?>
