But what I gave was a simple case. There are all kinds of complications like this person_record being passed around from call to call without actually accessing `.telephone` in a particular scope. Or doing something dynamic with the attributes/keys that won't show up in a `grep telephone`. Or the string telephone occurring lots of times in unrelated structures/objects. Or lots of other cases where lots of name changes makes refactoring more difficult. I mean, I've DONE it, and I'm sure you have as well. Clearly refactoring isn't impossible with different names across scopes... and this goal is one of several in picking names, not the single predominant one. > > -- > Richard Damon > _______________________________________________ > 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/PFSCBT3GATRPUPSQR4DFX4SVCJXFJUTH/ > Code of Conduct: http://python.org/psf/codeofconduct/ > -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons.
