We already have a bunch of bizarrely unrelated stuff in collections

Why not just "enum" (i.e., "from enum import [...]" or "import
enum.[...]")? Enumerations are one of the basic kinds of types overall
(speaking informally and independent of any specific language) - they
aren't at all exotic.
Enumerations aren't a type at all (they have no distinguishing
property).
Each enumeration is a type (well, OK, not in every language, presumably,
but certainly in many languages). The word "basic" is more important than
"types" in my sentence - the point is that an enumeration capability is a
very common one in a type system, and is very general, not specific to any
particular application.
And "Flat is better than nested", after all.
Not when it means creating a separate module for every micro-feature.
Classes have their own keyword. I don't think it's disproportionate to
give enums a top-level module name.
Having said that, I understand we're trying to have a not-too-flat module
namespace and I can see the sense in putting it in "collections". But I
think the idea that enumerations are of very wide applicability and hence
deserve a shorter name should be seriously considered.
I'll leave it at that, except for:
Hey, how about this syntax:
enum Colors:
red = 0
green = 10
blue
(blue gets the value 11)
