Well, it might be, but that would be very implementation-dependent.
Any attempt to treat an id as a memory address and interpret the
object at that address as the beginning of a PyObject of any kind will
be fragile in the extreme. Even if you have two different
implementations at hand which both use memory addresses as convenient
ids, there's no guarantee that the address represents that start of a
CPython PyObject.

>>> hex(3235346364)
'0xc0d777bc'

There. *Now* you have an address. Hack to your heart's content. <wink>
