SPUG: OO Perl object backrefrence question

	I have taken a look at the weaken() function, and have a further question
about it.
	I want to use it in my objects, but I would also like to store the objects
to a database via the Apache::Session mechanism and reuse them during a
session (so I don't have to do all the complex db queries required to build
the objects every time).
	My question is this:  Will an object that comes back from stored still have
references to it's parent weaken()ed?  I took a look at how Dumper() deals
with it and it doesn't seem to weaken() the references that it gives back,
so I'm worried.  I don't know how to tell how the reference comes back from
being stored (weak or not).

There's an article by Matt Sergeant on Perl.com right now that covers
exactly this.


Basically it shows how to pass a parent object to a child without creating a
circular reference.
