Right, unfortunately I need to add (or replace, if I added a nil, as you
say)
the values on an existing function.  I'm not within this function, nor do I
want
to call it right now.  When I initially create the Closure, I don't have any
way to tell if I will later need to add an upvalue or not.  I guess I might
have
to add a function within Lua to do it.
