Try jsonlight.dumps it'll just work.

Is the data only being read by python programs? If so, cons

You can achieve round-tripping by maintaining a type mapping in code, for a
single datatype it would look like:
newloads(datetime, newdumps(datetime.now())
If those would rely on __dump__ and __load__ functions in the fashion of
pickle then nested data structures would also be easy:
@dataclass
c

While I applaud your experimentation, that is not suit

Well I made a suggestion on python-ideas and a PyPi lib came out of it, but
since you can't patch a lot of internal types it's not so useful.

Hi,
I have a program that does a lot of work with URLs and requests,
collecting data over about an hour, & then writing the collated data
to a JSON file. The first time I ran it, the json.dump failed because
there was a bytes value instead of a str, so I had to figure out where
that was coming fr
