Within the Python context, the analogy from setattr and setitem at the
Python level to Py_SETREF at the C level is pretty solid, so it likely
makes sense to run with that as "good enough".

In regards to Py_MOVEREF, while other languages are starting to pay
more attention to "MOVE" semantics, we haven't really done so in
Python yet (moving references in Rust isn't the same thing we're
talking about here - this is just normal runtime reference counting).

Cheers,
Nick.
