I checked your modfication to funcall, so I see a closure can be a
two-element vector [fn env], which is very nice.  But then why do you
also use element 7 in byte code objects?

I think that's great!  I've been reading up on Common Lisp
"funcallable instances", which are function objects that are
simultaneously class instances.  With standard byte code objects, I
could store instance slots in an unused byte code element, but with
funcallable vectors, I can store the slots in the vector.
