Fissix

Fissix is a Python library that monkeypatches and overrides the default behavior of the standard library `lib2to3`. It provides an enhanced and actively maintained version of `lib2to3`, primarily used for transforming Python code, especially for backporting `2to3` fixes for Python 3 codebases. It aims to be a drop-in replacement for `lib2to3`'s code transformation utilities. The current version is 24.4.24, and it often sees updates in conjunction with CPython development.
