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: namespace.rb
    path of file: ./repos/rbs/lib/rbs
    
    the code of the file until where you have to start completion: # frozen_string_liter
    
    def to_type_name
      parent, name = split

      raise unless name
      raise unless parent

      TypeName.new(name: name, namespace: parent)
    end
