I have to agree with that. Enums can live in a module (together with
stuff that uses them) or in a class (if all the uses are limited to
that class); they don't need an extra namespace of their own.
The standard examples using homonyms in unrelated enums are typically
missing the fact that Python doesn't really have *global* variables --
only "module-global", which is really quite narrowly scoped.
If a single module or package is exporting so many enums that extra
scoping is considered useful, it's easy enough to introduce an extra
namespace using existing mechanisms (e.g. a class or a submodule).
