Is there any reason why date, datetime, and UUID objects automatically serialize to default strings using the csv module, but json.dumps throws an error as a default? i.e.

import csv

import json

import io

from datetime import date

stream = io.StringIO()

writer = csv.writer(stream)

writer.writerow([date(2018, 11, 2)])

# versus

json.dumps(date(2018, 11, 2))
