It seems like this could be a good use case for pattern matching...
try:
...
raise Exception(a, b, c, d, e, f)
except Exception as e match e.args:
case (a: int, b: str, c, _, _ f):
logger.warning(f"BAD THING {a} HAPPENED!")
if not handle_it(a, b, c, f):
raise
[Incidentally PEP 634 is very light on actual examples, and I'm having trouble
visualizing what the syntax actually looks like, so please forgive me if I
misunderstood what the pattern should look like]
