Description: There are currently some code paths that use __new__ and __init__ directly instead of going through the Constructor/Initializer. I plan to change these so that they raise an error. Before doing that, we’ll need to remove any code that actually relies on this behavior. close #6448 Summary by CodeRabbit Refactor Centralized and reworked object and exception initialization to a trait-based initializer/constructor system. Many built-ins and exceptions now use the new initialization pathway (no visible behavior change; construction semantics preserved). Some previous public init implementations were removed and replaced by the new initializer-based flow (e.g., Cursor), preserving external behavior. ✏️ Tip: You can customize this high-level summary in your review settings.
