This leaves one use of __dict__ used for iterating through attributes.
I could use dir() instead, but I was put off by this note in its
documentation in the Python Library Reference:
Because dir() is supplied primarily as a convenience for use at an
interactive prompt, it tries to supply an interesting set of names more
than it tries to supply a rigorously or consistently defined set of names,
and its detailed behavior may change across releases. For example,
metaclass attributes are not in the result list when the argument is a
class.
