Ethan, I don't understand what the problem is. I also don't understand your
side note question how does partial-ordering work for sets? I'm not sure what
you're asking.
That is, one counter will be considered smaller-or-equal to another if for
any
item
Ram Rachum added the comment:
To put it another way: In Python sets, `a = b` iff `b` has everything that `a`
has, and possibly more. I'm proposing the exact same definition for counters.
True, the implementation might be different because sets are not dicts and
don't have `.values

New submission from Ram Rachum:
I suggest making Enum members orderable, according to their order in the enum
type. Currently trying to order them raises an exception:
import enum
class Number(enum.Enum):
... one = 1
... two = 2
... three = 3
sorted
New submission from Ram Rachum:
I'd like Enum objects to expose their serial numbers. Currently it seems the
only way to get this is `MyEnum._member_names_.index(my_enum.name)`, which is
not cool because it's cumbersome and involves private variables.
Perhaps we can use `int(my_enum) == 7

Calling `dir` on an enum subclass shows only the contents of that class, not
its parent classes. In normal classes, you can do this:

Another use case I can think of is that if you store enum values in a database,
you're probably using an int field and you'd want to easily convert between an
enum and it's int value
Ram Rachum added the comment:
Just because I want to be able to get the `int` value of an enum object,
doesn't mean I want the enum object to *be* an `int`, which is what `IntEnum`
means. I don't want it to be comparable to an int, I don't want to use
arithmetic on it, and most importantly I
Ram Rachum added the comment:
My particular use case is that I have objects with a tuple of enum objects to
each, and I want the tuple to be in canonical order rather than random, for
convenience.
I can easily use a subclass, but I think it's general enough functionality

As I said in the other ticket: I can easily use a subclass, but I think it's
general enough functionality for it to be included in the standard library.

Ram Rachum added the comment:
Enum members are also defined to be unordered, so their serial number is
meaningless.
Are you sure? The documentation says Enumerations support iteration, in
definition order and shows how `tuple(MyEnum)` outputs the values in
definition order.
