Allow certain short argument/variable names that make perfect sense

[matkoniecz]

Is your feature request related to a problem? Please describe

pylint complains about variable/argument names like x, y.

Describe the solution you'd like

Whitelist variable names that are typically OK despite being really short

Additional context

See https://github.com/mkenyon/rubocop/blob/master/config/default.yml#L792 for how Rubocop (linter for Ruby) solves it for their UncommunicativeMethodParamName equivalent

See #2018 for a related problem where short names are misleadingly described as not being snake_case

Please check the good-names option, which does exactly this.

And what about function/method names? A function with a 2-letter name gives an warning. I don't see a good-func-names option.

@gitaarik You are probably interested in configuring function-rgx: http://pylint.pycqa.org/en/stable/user_guide/options.html. There is no good-func-names because it does not make sense to have one. While good-names is a finite number of variables names, a function name cannot be easily determined to be good or not.

Sorry, the good-names option apparently does work for me! I was just editing the wrong file 😂. Thanks anyway.
