Pattern: Missing use of self for class/module method

Issue: -

Description

This rule checks for uses of self when defining class/module methods. This makes the code easier to refactor since the class name is not repeated.

Examples

# bad
class SomeClass
  def SomeClass.class_method
    ...
  end
end

# good
class SomeClass
  def self.class_method
    ...
  end
end
