Of course it must be defined in C so that one can initialize the
names of objects properly.  I'm not sure whether it ought to be
mutable or not.  A "write-once" property might be useful..

  (define name (make-read-only-property))

  (name obj) => #f          ;; or undefined error
  (set! (name obj) 'foo)
  (name obj) => foo
  (set! (name obj) 'bar)    ;; immutable error
