I'm still trying to digest this with very little time for it. It *is* slightly confusing. Perhaps it would be possible to name the data structures by their functionality. E.g. if ExecutionContext is a stack, use ExecutionStack? Or if the dynamic scope angle should be highlighted, perhaps ExecutionScope or even DynamicScope. This sounds like bikeshedding, but I find it difficult to have ExecutionContext, ContextItem, LocalContext in addition to the actual decimal.localcontext() and PyDecContext. For example, should PyDecContext inherit from ContextItem? I don't fully understand. :-/ Stefan Krah _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
