Ethan's email suggests that against my advice he is in-fact going to go through the standard library, applying enums quite broadly.
That is somewhat at odds with the notions of holistic refactoring and gradual change. Nor does it reflect sufficient appreciation for concerns about maintenance issues, code stability, the effect on 2-to-3 migration, doctests, performance, the wishes of the module authors, or whether users will see any actual benefits (particularly for internal constants).
I fully understand the enthusiasm to take the car out for a spin, but the standard library isn't really a great place for experimentation. And "trying to learn the standard library" isn't a good rationale for making extensive changes to it.
So, please do help make sure there is some restraint and careful consideration.
