I must say I never understood how exactly is assigning a constant better in
this regard. To me, after
a = SOMETHING
b = SOMETHING
a and b should be the same, right? _Especially_ when SOMETHING is None or (),
but also when it's some bare identifier like AUTO_ENUM.
Mental models are already broken. We are already "lying" according to semantics
of type metaclass. There is no reason then to have to sprinkle some magic dust
over our code, just so it looks like an assignment is the most important thing
here, when it really isn't.
Either we should embrace Python's power in full and communicate to users that
there's something weird going on, or we shouldn't have AutoEnum. To me, `green
= None` is in no way better, in fact it seems more dishonest, than simply
`green`. Again, _if_ we communicate (e.g. via style='declarative') that the
semantics is not ordinary. (Alternatively, we might just write `green =
uuid4()` and be done with it.:)
