I'd be curious to know what alternatives you see. When a user writes `x + y` with both `x` and `y` instances of `decimal.Decimal`, the decimal module needs to know what precision to compute the result to (as well as what rounding mode to use, etc.). Absent a thread-local context or task-local context, where would that precision information come from? _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/INXN3XOM24N6EZUFYV6O3FAKK6UXBVP5/ Code of Conduct: http://python.org/psf/codeofconduct/
