I also see inconsistent behaviorbetween the enumerate() functions in threading
and dummy_threading:
Python 3.7.3 (default, May 1 2019, 00:00:47)
[Clang 10.0.1 (clang-1001.0.46.4)] on darwin

>>> from threading import Thread
>>> from threading import enumerate
>>> enumerate()
[<_MainThread(MainThread, started 4618048960)>]
>>> def f(): print('foo')
...
>>> t = Thread(target=f)
>>> enumerate()
[<_MainThread(MainThread, started 4618048960)>]
>>> t.start()
foo
>>> enumerate()
[<_MainThread(MainThread, started 4618048960)>]
>>> t.is_alive()
False
>>> enumerate()

>>> t.join()
>>> enumerate()
