A true ternary C op a po b has no such ambiguity.  Every op must be
matched by a following po.   Every po matches the nearest preceding
unmatched op.  Just as with (), [], etc.  Possible ambiguity arises in
conditional statement trees because  'else: pass' is allowed to be
omitted.  But conditional expressions *must* evaluate to something in
all branched of the logic tree.
