# bad
attr_accessor :foo
def do_something
end

# good
attr_accessor :foo

def do_something
end

# good
attr_accessor :foo
attr_reader :bar
attr_writer :baz
attr :qux

def do_something
end

AllowAliasSyntax: true (default)

# good
attr_accessor :foo
alias :foo? :foo

def do_something
end

AllowAliasSyntax: false

# bad
attr_accessor :foo
alias :foo? :foo

def do_something
end

# good
attr_accessor :foo

alias :foo? :foo

def do_something
end

AllowedMethods: ['private']

# good
attr_accessor :foo
private :foo

def do_something
end
