One universally available improvement requires no special compilation: the interactive interpreter (REPL) has been completely rewritten based on PyPy's implementation. The new REPL supports multi-line editing with seamless block handling, colorized syntax highlighting, and persistent command history across sessions. Exception tracebacks are now colorized by default, with different colors distinguishing error types, file paths, and line numbers.

The locals() built-in function now has well-defined semantics when mutating the returned mapping, which allows debuggers to operate more consistently.
