First of all, I don't agree that variables are first class
objects in any of the above languages.
----------------------------

Yes... perhaps the confusion is my fault.  I guess I should not have said
`variables'... I meant `bindings'.

Though, in thinking about this more, I think that good 'ol C has this;
they're called pointers.  And in C you can have pointers to pointers, but in
the "everything is a pointer" languages, I guess you really *can't* have
pointers to pointers (or bindings and first-class objects).  I think...

Anyway, I think I understand the pros and cons of that now.  I guess you
could have some sort of mechanism for this in a language like Ruby... but I
don't see why you'd want it.
