Based on the diff, the pull request modifies the tuple_arbitrary.mbt file, which appears to be part of a testing or quickcheck framework in the MoonBit language. The main change is related to the Arbitrary trait alias.

Summary of Changes:

1. Trait Alias Modification: The trait alias Arbitrary is changed from @quickcheck.Arbitrary to just @quickcheck.Arbitrary. This seems to be a simplification or correction of the trait alias syntax.

Review:

⚠️ [Potential Typo in Trait Alias]

• Category: Correctness
• Code Snippet: traitalias @quickcheck.Arbitrary
• Recommendation: Ensure that the trait alias is correctly defined. If Arbitrary is intended to be an alias for @quickcheck.Arbitrary, it should be written as traitalias Arbitrary = @quickcheck.Arbitrary.
• Reasoning: The current change removes the Arbitrary alias, which might lead to confusion or errors in the codebase. If the intention was to simplify the syntax, it should still maintain clarity and correctness.

💡 [Need for Documentation]

• Category: Maintainability
• Code Snippet: pub impl[A : Arbitrary, B : Arbitrary] Arbitrary for (A, B) with arbitrary(
• Recommendation: Add a brief comment or documentation explaining the purpose of this implementation block, especially if it's part of a testing framework.
• Reasoning: Proper documentation helps other developers understand the purpose and usage of the code, making the codebase easier to maintain.

Overall:

The change seems minor but could have implications on the correctness and clarity of the code. It's important to ensure that the trait alias is correctly defined and that the code is well-documented for future maintainability.
