Python is supposed to be duck-typed. It would be strange to add a
couple of random exceptions to that general rule. Moreover, having to
*both* derive an existing class and implement the single method defined
on that class is one complication too many.

And I don't see how `__json__` is more annoying than e.g. `to_json`.
