... to numify a reference to something other than an actual memory address ...

In the non-reference counting, brave new world of mark&sweep GC, it probably will break it, but it begs requires the question of whether there will be some mechanism for asking the VM about circular references.

How do other systems that use mark&sweep allow traversals of potntially circular structures to detect that?
