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: mock.rb
    path of file: ./repos/ruby/spec/mspec/lib/mspec/mocks
    
    the code of the file until where you have to start completion: require 'mspec/expectations/expectations'
require 'mspec/helper
    
  def self.mock_respond_to?(obj, sym, include_private = false)
    name = replaced_name(obj, :respond_to?)
    if replaced? name
      obj.__send__ name, sym, include_private
    else
      obj.respond_to? sym, include_private
    end
