Ok, so if the SV is actually an reference to an AV, and the latter transitively goes to zero refcnt, is the AV freed? And, if so, are the elements of the AV similarly handled? I'm confused as to whether I get comprehensive management for "free" in the XS world, or whether the burden is on me to iterate into complex data structures. Steve
