Yes, that's what I mean by "bound to some anonymous thing".
Somewhere in the implementation there must be one or more
"root" references, but they don't necessarily have any names
that you can refer to from Python.

When I say "not bound to any name", I just mean that it's
okay to leave some bindings out of your diagram if they're
not pertinent to what you're trying to illustrate. For
example, you can draw a box representing a string object
and trust that something will keep it alive long enough
for you to draw an arrow to it from the name you're
assigning it to.
