One specific question:
For most refcounted objects, a nonzero refcount means "this object is in use", and a zero refcount means "this object is no longer in use, you can free it now". For GC::Anchored objects, refcounting is merely an override to the normal operation of the garbage collector, so the rules are relaxed somewhat: a nonzero refcount merely means "the object is in use in places that the garbage collector can't see", and a zero refcount asserts that "the garbage collector can now see every use that matters".
Can you please define "places that the garbage collector cannot see"? How do I find out if I'm in such a place or not?
