Inconsistent alias naming pattern across the codebase

Category
Maintainability
Code Snippet
Lines 185, 232, 281 in arrayview.mbt and similar lines across other files:
#alias("[:_]")
Recommendation
Consider using a consistent naming convention. The new alias "_[_:_]" is more descriptive than op_as_view, but ensure this pattern is documented in the style guide for future alias definitions.
Reasoning
The change improves readability by using a more intuitive slice syntax, but having a documented pattern for alias naming helps maintain consistency across the codebase.

Missing validation that all references to the old alias are updated

Category
Correctness
Code Snippet
All occurrences of #alias(op_as_view) changed to #alias("[:_]")
Recommendation
Verify that any code, tests, or documentation that references the old op_as_view alias has been updated to use the new slice syntax [start:end]. Run a comprehensive search for any remaining references.
Reasoning
Changing an alias without updating all references could break existing code that depends on the old syntax, leading to compilation errors or unexpected behavior.

Large scope change affecting multiple modules simultaneously

Category
Maintainability
Code Snippet
Changes span across builtin/arrayview.mbt, builtin/iter.mbt, builtin/uninitialized_array.mbt, bytes/view.mbt, string/view.mbt and their corresponding .mbti files
Recommendation
Consider breaking this into smaller, module-specific commits or ensure comprehensive testing covers all affected data types. Add integration tests that verify the new slice syntax works correctly across all types.
Reasoning
While the change is consistent, modifying aliases across multiple core data structures simultaneously increases the risk of introducing subtle bugs. Smaller, focused changes are easier to review and debug.
