Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request finalizes the deprecation of the T.Bind API by eliminating its backward-compatible alias and updating all existing usages to the new T.bind function. This change streamlines the API, promotes consistent naming conventions, and cleans up the codebase by removing an outdated alias.

Highlights

• API Renaming Cleanup: The backward-compatible alias T.Bind has been completely removed, enforcing the use of the standardized T.bind function.
• Codebase Modernization: The Bind = bind alias was removed from ir.py, and all internal references to T.Bind across the codebase were updated to T.bind.
• Export List Update: The string "Bind" was removed from the __all__ exports in ir.py to reflect the API change.
