I think this thread can be resolved as 'used unittest.mock.sentinel'. It doesn't have 'global sentinels', but I'm not convinced they are actually necessary, since `mock.sentinel` objects with the same name compare as equal. Thanks to Nathaniel, I now understand that JS has global symbols for historical reasons that we don't have, and I'm not convinced of their usefulness.
Do all Python distributions ship with unittest.mock? I see to recall that Debian and/or Ubuntu strips out part of the normal distribution. For example, dataclasses.py has a sentinel, and it includes some code to get a more helpful repr. It would make sense to re-use the unittest.mock.sentinel code, but not if that code isn't always guaranteed to be present. Eric
