    @num = num
  end

  def around(function, method_name, this, *args, &block)
    puts "log #{@num} invoke #{method_name}"
    function.call(method_name, this, *args, &block)
  end
end

SimpleAspect.add_impl :log1, LogAspectImpl.new
SimpleAspect.add_impl :log2, LogAspectImpl.new(2)

A.new.abc

# Expected output
# log 1 invoke abc 
# log 2 invoke abc 
# abc
