[issue18264] enum.IntEnum is not compatible with JSON serialisation

[Ethan Furman]

Ethan Furman added the comment:

I was unable to find any references to previous problems with json and floats.  A quick-n-dirty patch yields the following:

--> from json import dumps, loads
--> from enum import Enum
--> class FE(float, Enum):
...   pass
... 
--> class Test(FE):
...   one = 1.0
... 
--> Test.one
<Test.one: 1.0>
--> str(Test.one)
'1.0'
--> dumps(Test.one)
'1.0'
--> loads(dumps(Test.one))
1.0

All json and enum tests are still passing.

If this is an acceptable solution I'll create a nicer patch and post for review.
