Even there, I'd most often use "except BaseException as e:", other
than in a very few situations. The only time I have recently used a
bare except is when making use of the traceback module:
try:
 ...
except:
 with open("notes.err", "a") as err:
 traceback.print_exc(file=err)
 raise
since print_exc() can go fetch the exception via sys.exc_info().
