If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

Looks good. I have a PR open for the test runner Docker image, and I'm working through a few bits with Isaac before that's good to go.
