I think that would work very nicely with [tie]. I'm not sure about object
reference counts, though. While the object destruction with [tie] can
be thought of as a link to a variable (ie. the variable could be declared
to do that) but I see auto-destruction of an object when refs are lost
to be an attribute of the object, not of the variable which it is assigned
to. I mean, with ref counting, that variable could easily disappear, but
the object would still exist if there are references.
