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: pyobject_wrapper.rb
    path of file: ./repos/pycall.rb/lib/pycall
    
    the code of the file until where you have to start completion: require 'pycall/wrapper_object_cache'

module PyCall
  module PyObjectWrapper
    attr_r
    
    def method_missing(name, *args)
      name_str = name.to_s if name.kind_of?(Symbol)
      name_str.chop! if name_str.end_with?('=')
      case name
      when *OPERATOR_METHOD_NAMES.keys
        op_name = OPERATOR_METHOD_NAMES[name]
        if LibPython::Helpers.hasattr?(__pyptr__, op_name)
          LibPython::Helpers.define_wrapper_method(self, op_name)
          singleton_class.__send__(:alias_method, name, op_name)
          return self.__send__(name, *args)
        end
