Python already as dereferenceable addresses. Look.
def address(obj,table=[]):
for i,o in enumerate(table):
if obj is o: return i
table.append(obj)
return len(table)-1
def deref(addr):
return address.__defaults__[0][addr]
You can take the address of an object (interning it, effectively), and
later dereference it. Proves nothing.
