We can land the fix first and the examples and tests later.

I agree with the suggestions made in this thread about examples and
cases. Let's have the example like Alice suggest and then test boundary
inputs in `#[test]` kunit tests. Define the magic numbers as named
constants local to the test scope, not as part of the exported API.
