While I agree entirely with your point, there is however perhaps room
for a bit more helpfulness from the json module. There is no sensible
reason I can think of that it refuses to serialize sets, for example.
Going a bit further and, for example, automatically calling isoformat()
on date/time/datetime objects would perhaps be a bit more controversial,
but would frequently be useful, and there's no obvious downside that
occurs to me.
