You only need a binary flag to indicate if a comma is needed, not a
stack.  We need a comma at the current level if and only if we already
wrote a child item.  If we finish a level then we do need a comma at the
previous level because we just wrote a sub-object or sub-array there.
And that should cover all cases.  Am I missing something?

I get a sense of déjà vu, by the way. :)

Yes, your way is simpler.  I'll update and re-roll.
(And yes, we did discuss this earlier.  I found a problem with
my first version where it wouldn't handle empty sub-items, but
you found the missing piece.)
