I've had a short discussion with Anthony about this and he convinced me
that I was indeed wrong about my "unary minus" reasoning; therefore I have
updated the RFC to reflect that. So:

echo -3 ** 2; // 9
echo 1 - 3 ** 2; // -8

The unary minus is now at the same level as `[`, the array dereferencing
operator.
