This is one reason 'no addition' got a relatively high rank in the vote.

I still stronly prefer this order and even slightly prefer this form.  I 
might even prefer a complete inversion of the order: x else y if c
                             'DO' else 'DONT' if cmd != DO
except that that does not chain at all well.
