If a user has

     class Color(StrEnum):
         red = 'ff0000'
         green = '00ff00'
         blue = '0000ff'

..
..
..

oh.  `str()` isn't going to give is the `value`'s string, is it?

Hmmm...

Instead of calling int() or float() on an enum member, perhaps we could make json smart enough to use the `value`?  That 
would also cover pure Enums.
