I agree with @smarter's comment on #3928 that it would be good to have a bytecode test. I don't know enough about the bytecode testing framework to be able to do one quickly, though. So if someone else wants to add one, please do!

The CI failure should go away after rebasing. I can do it while adding a bytecode test

@allanrenucci Thanks for the test!
