Review comment:
Yeah. This is super confusing naming. Just to clarify:
- `allow_nan=False`: will raise an exception if the data has NaN/Infinity;
- `ignore_nan=True`: will encode NaN/Infinity as nulls.
I'm assuming what happened was that someone had an async query returning
NaN/Infinity, and since the stdlib `json` module does not have the `ignore_nan`
argument the easiest way is to work around is to raise an exception here. It
took me a while to learn that `simplejson` had this option.
I looked at the blame and couldn't find any info about this. The reason I
changed this as well was to make it consistent with the sync call.
