backrefs

backrefs is a Python library that extends the functionality of the standard `re` module and the third-party `regex` module by adding additional back references. It introduces features like `\c` for character class back-references, `\k<name>` for named capture groups that act as character classes, and enhanced atomic grouping. The library maintains an active development status, with regular minor releases addressing new features, bug fixes, and Python version compatibility.
