Some late nitpicking, sorry: This is not an atomic counter, it's a thread-safe counter. And since being thread-safe is rarely a bad idea, especially assuming someone will manage to Kill GIL, I would just call it a "counter" or Counter. (Of course, atomic/lock-free implementations are nice when possible.) -- Koos _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
