New submission from Connor Wolf:
The Python library JSON library doesn't emit JSON by default.
Basically, `json.dumps(float('nan'))` produces something that kind of looks
like json, but isn't (specifically, `'NaN'`). Valid JSON must be `null`.
JSON *does not allow `NaN`, `infinity`, or `-infinity`.
`json.dump[s]` has the parameter `allow_nan`, but it's `False` by default, so
basically it's not actually JSON by default.
The default for emitting JSON should actually emit JSON. `allow_nan` must be
`True` by default.
