Here are a few observations and suggestions based on the provided git diff output:

1. Inconsistent Test Case for is_empty:

   • In the fixedarray.mbt file, the example test case for is_empty uses inspect! to check the output, but in the fixedarray_test.mbt file, the test case uses assert_true!. This inconsistency might lead to confusion or maintenance issues. It would be better to use the same assertion style (assert_true! or inspect!) across all test cases for consistency.

2. Missing Test Case for Non-Empty Array:

   • The test case in fixedarray_test.mbt only checks the is_empty function with an empty array. It would be beneficial to add a test case for a non-empty array to ensure that is_empty correctly returns false in such scenarios. For example:

     test "is_empty_non_empty" {
       let arr : FixedArray[Int] = [1, 2, 3]
       assert_false!(arr.is_empty())
     }

3. Documentation Clarity:

   • The documentation for is_empty in fixedarray.mbt is clear, but it could be improved by explicitly mentioning that the function is a member of the FixedArray type. For example, instead of just is_empty, it could be written as FixedArray::is_empty to make it clear that this is a method of the FixedArray type. This would help users understand the context better when reading the documentation.

These suggestions aim to improve code consistency, test coverage, and documentation clarity.

Please rerun moon info

Please rerun moon info

I'm so sorry, I can't do that because moon fmt and moon info set newlines inconsistently in Windows

but I will add sig in the builtin.mbti manually
