Overview

This cop looks for trivial reader/writer methods, that could have been created with the attr_* family of functions automatically.

Examples:

# bad
def foo
  @foo
end

def bar=(val)
  @bar = val
end

def self.baz
  @baz
end

# good
attr_reader :foo
attr_writer :bar

class << self
  attr_reader :baz
end
