It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group. |

There was a problem hiding this comment.
I think "The Caching Iterable" looks kinda silly, but since it's following a pattern from other tests in this file it's all good 👍

There was a problem hiding this comment.
Not really in the scope of this PR, but we should probably migrate to the new API at some point:
- class CachingIterable<E> extends IterableBase<E> {
+ class CachingIterable<E> with Iterable<E> {

Sorry, I didn't manage to get the tests running locally so I can't test before pushing! Hopefully it's all good now. |

google test failure doesn't seem related, rerunning to see if it passes |
