[docs] [issue22297] 2.7 json encoding broken for enums

[Edward O]

Edward O added the comment:

The arguments for fixing:

* int subclasses overriding str is a very common usecase for enums (so much so that it was added to stdlib in 3.4).

* json supporting a standard type of a subsequent python version, though not mandatory, would be beneficial to Py2/Py3 compatibility.

* fixing this cannot break existing code

* the fix could theoretically be done to 3.0-3.3 if Ethan's argument is deemed important.
