Indeed.  Other thing: please try and think about the impact those field
might have on the round-tripping of data through JSON (i.e. how to make
it so that decoding the JSON output back to Elisp gives equivalent data).

I think this :print-function is now obsolete since it was meant to
hook into `princ`, but that can now be done in cl-print.

I don't think :print-function and cl-print can be of much use for
encoding to JSON.
