Thank you so much @zeckson for working on improving this coverage.

We probably don't need this test, but there's nothing wrong with including it.

It may be valuable to capture the default behavior. If we'd ever (accidentally) flip the default type, this would fail. Though realistically a lot of tests would fail then...

It could also be worth making this a test of import.meta.url. Note that such a test would be the exact test needed to fix #28160 (comment).

I would be a bit concerned that it would increase the test scope. E.g. this test is meant to verify that the source is run as a module. If we change the exact string in import.meta.url in the future, it would break this test even though the source is still running as a module. If we want to test specific behavior ("relative imports work in --eval"), I would prefer a dedicated test for that.

@jkrems Does this look good to you? (No pressure or anything, obviously, but I'm just asking becauseI'd prefer to land it with more than one approval.) |
