Ethan thinks that "Seasons(3)" is a typecast, not an access into a mapping (which would be better expressed by "Seasons[3]"). Ie, the inverse of "int(AUTUMN)". This is consistent with the "AUTUMN is-a Seasons" position that Ethan and Guido take. It's inconsistent with the "AUTUMN is-a Seasons_VALUE" implementation of Flufl.Enum. @Ethan: I have real trouble sympathizing with your point of view because you consistently pluralize your Enum names. AUTUMN *is not* a SeasonZZ, it is an element of the *collection* Seasons. OTOH, AUTUMN *is* a Season (look Ma, no ZZ!) I wonder if you might not get more sympathy from Guido if you named your Enums with the singular form. Note that for some reason I don't have the same problem if Barry names an Enum "Season" (no ZZ!) I don't know why, maybe because the semantics of type is to define a collection (which in English is invariably denoted by the plural of the type name), so there's implicitly a plural there. But I'm not confident in that psychoanalysis. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
