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: data.rb
    path of file: ./repos/natalie/src
    
    the code of the file until where you have to start completion: class Data
  def self.define(*member
    
  def self.define(*members, &block)
    members = members.map(&:to_sym)

    Class.new do
      members.each do |name|
        define_method(name) { instance_variable_get(:"@#{name}") }
      end

      define_method(:initialize) do |*args, **kwargs|
        if args.empty? && !kwargs.empty?
          kwargs = kwargs.transform_keys(&:to_sym)
          missing = members - kwargs.keys
          unless missing.empty?
            raise ArgumentError, "missing keyword#{missing.size == 1 ? '' : 's'}: #{missing.map(&:inspect).join(', ')}"
          end
          extra = kwargs.keys - members
          unless extra.empty?
            raise ArgumentError, "unknown keyword#{extra.size == 1 ? '' : 's'}: #{extra.map(&:inspect).join(', ')}"
          end
          kwargs.each do |name, value|
            instance_variable_set(:"@#{name}", value)
          end
        elsif args.empty?
          raise ArgumentError, "missing keyword#{members.size == 1 ? '' : 's'}: #{members.map(&:inspect).join(', ')}"
        else
          if members.size != args.size
            raise ArgumentError, "wrong number of arguments (given #{args.size}, expected #{members.size})"
          end
