OpenReg did not need such things.  We lived in a world of database
tables, so storing a name of a zone or its zone_id was enough to
reference a shared object.

I could see a way to do this without any magic.  If you expect a node
named "parent" to be either a parent object (that is, a "hash"
describing the object) but get an integer, that references an object
with an id you already got.
