This strikes me as close to self-contradictory - you can't easily tell the difference precisely
because 99% of the time there is no difference.
If you think an undefined variable shouldn't raise a notice, then let's discuss
improvements to the way such messages are emitted so that it would be easier to adjust that
behaviour.
