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.
