You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: should.rb
    path of file: ./repos/jruby/spec/mspec/lib/mspec/expectations
    
    the code of the file until where you have to start completion: class Object
  NO_MATCHER_GIVEN = Object.new

  def should(matcher = NO_MATCHER_GIVEN, &block)
    MSpec.expectation
    state = MSpec.current.state
    raise "should outside example" unless state

    
  def should_not(matcher = NO_MATCHER_GIVEN, &block)
    MSpec.expectation
    state = MSpec.current.state
    raise "should_not outside example" unless state
    MSpec.actions :expectation, state

    if NO_MATCHER_GIVEN.equal?(matcher)
      SpecNegativeOperatorMatcher.new(self)
    else
      # The block was given to #should_not syntactically, but it was intended for the matcher
      matcher.block = block if block

      if matcher.matches? self
        expected, actual = matcher.negative_failure_message
        SpecExpectation.fail_with(expected, actual)
      end
