[issue6566] json.dumps converts None to "null" (not null)

[Bob Ippolito]

Bob Ippolito <bob at redivi.com> added the comment:

JP is correct, this is how JSON works. The behavior of coercing keys to 
strings is often desirable, although I agree it could be confusing if you 
aren't familiar with the JSON spec.
