It's a pretty complicated tool, actually - but you're using it in a
simple way here. If you're curious, you can poke around in the CPython
sources to track down the data structures involved - as you noted, the
refcount is at the beginning of every object, and after that you'll
find some neat info like a pointer to its type. You can even change
some of this stuff, but be aware that you can EASILY segfault Python
like this :D
