I know that a RB will destroy objects with no references

You have to get rid of all the references by nil'ing them or
having the objects holding the references go out of scope
There's no "kill this object"
There is a supplementary answer: weak references.
What would you want to have happen to the references to the object
when you destroy it? The only reasonable answer is: have them
become nil.
That's what a weak reference does: it refers to an object, but
doesn't stop it being destroyed, and when the object is destroyed,
it becomes nil.
Unfortunately, REALbasic doesn't have weak references. But if it
ever does acquire them, now you know what they're for. :-)
