devel/py-exceptiongroup 1.2.2 DragonFly

This is a backport of the BaseExceptionGroup and ExceptionGroup classes from Python 3.11.

It contains the following:

• The exceptiongroup.BaseExceptionGroup and exceptiongroup.ExceptionGroup classes
• A utility function (exceptiongroup.catch()) for catching exceptions possibly nested in an exception group
• Patches to the TracebackException class that properly formats exception groups (installed on import)
• An exception hook that handles formatting of exception groups through TracebackException (installed on import)

If this package is imported on Python 3.11 or later, the built-in implementations of the exception group classes are used instead, TracebackException is not monkey patched and the exception hook won't be installed.
