Following a recent change, we now have in traceback.py:
_sentinel = object()
def print_exception(exc, /, value=_sentinel, tb=_sentinel, limit=None, file=None, chain=True):
So now:
>>> import traceback
>>> help(traceback.print_exception)
Help on function print_exception in module traceback:
print_exception(exc, /, value=<object object at 0x000002825DF09650>, tb=<object object at 0x000002825DF09650>, limit=None, file=None, chain=True)
Is there a convention on how such default sentinel values should appear in docs?
