This would be a generic argument against any new feature. I don't think it is very compelling in this case. For people who develop on a latest version. these constants will pop up in sys.<tab> autocompletion and they will likely use them. If they need to support pre-3.5 versions,
try:
from sys import exit, EXIT_FAILURE
except ImportError:
from sys import exit
EXIT_FAILURE = 1
is not a hard work-around.
You would say, why not just use EXIT_FAILURE = 1 to begin with? To avoid Bob using EXIT_FAILURE = -1, Alice using EX_FAIL = 1 and Karl
giving up and using exit(1) in perpetuity. |
