Well, a typical Linux install includes "errno" util:
$ errno 13
EACCES 13 Permission denied
So, hail to error numbers. And indeed, even if some may think they're
artifact of 1980'ies, they're alive, well, and useful:
$ pylint --help-msg W1651
:deprecated-itertools-function (W1651): *Accessing a deprecated function on the itertools module*
Used when accessing a function on itertools that has been removed in Python 3.
This message belongs to the python3 checker. It can't be emitted when using
Python >= 3.0.
