Based on the diff and pull request message, the purpose of this change appears to be adding a test case for stack overflow in the unzip operation of lists in MoonBit. The test creates a large list, zips it with itself, and then attempts to unzip it.

Here's my review:

💡 [Test case could be more descriptive and focused]

• Category: Maintainability
• Code Snippet:

test "stack overflow test/unzip" {
  let iter = Int::until(0, 1 << 13)
  let xs = from_iter(iter)
  let ys = xs
  let zs = xs.zip(ys)
  zs |> ignore
  zs.unwrap().unzip() |> ignore
}

• Recommendation: Rename the test to be more specific and possibly split it into multiple focused tests

test "unzip should handle large lists without stack overflow" {
  let large_list = Int::until(0, 1 << 13) |> from_iter
  let zipped = large_list.zip(large_list)
  zipped.unwrap().unzip() |> ignore // Expect no stack overflow
}

test "zip should handle large lists" {
  let large_list = Int::until(0, 1 << 13) |> from_iter
  large_list.zip(large_list) |> ignore // Expect no stack overflow
}

• Reasoning: The current test name is vague and the test is doing multiple things (testing both zip and unzip operations). By splitting it and using more descriptive names, the purpose of each test becomes clearer, making it easier to identify which specific functionality failed if there are issues.

This is the main issue I noticed. The test itself appears to be valid and correctly tests the stack safety of these operations, but could be improved for better maintainability and clarity. Otherwise, the change seems good and addresses an important edge case (large lists) that could cause stack overflow issues.
