Justin Lebar added the comment:
Ah, I see. The examples do what you think they should do, but not for the reason you think they should do it -- the JSON encoding logic calls the encoder's encode() method before calling its default() method.
I still think the examples could be improved, perhaps by adding a comment to the effect of 
 # Raises a TypeError.
before the call to JSONEncoder.default(). Explicit is better than implicit, after all. :)
Thanks for looking at this.
