Overview

Checks to make sure class variables are not being used..

Class variables in Ruby have a complicated inheritance policy, and their use can lead to mistakes. Often an alternate design can be used to solve the problem instead.

This check is looking for a code smell rather than a definite error. If you’re sure that you’re doing the right thing, try turning this check off in your config file.
