messed up. Or is that not possible, and yet another way that GG is

Doh. True, I should have said "If a is not None and a is not None, use a".
But my point about unintended behaviour if a is None stands. And
the wider point that these operators are hard to reason correctly
about is probably emphasised by my mistake.
