_sunder_ methods are reserved for internal Enum use, and if the user tries to use any an exception is raised.Consequently, the enum34 backport uses __order__ instead of _order_ to specify a definition order for its members.I would like to do two things:1) add _order_ to the stdlib version2) ensure the actual definition order is the same as what is specified   in _order_

Doesn't namedtuple use _fields (as opposed to _fields_) for a similar purpose? Would Enum using _order be more consistent with that?

It would, but that's not what we did.Currently we have _name_ and _value_; the backport uses __order__ because I didn't want the stdlib version having a hairball when someone tried to use a 2.7 Enum in 3.4 and it didn't occur to me at the time to just add and ignore _order_.
