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: generic_object.rb
    path of file: ./repos/stackneveroverflow/vendor/bundle/ruby/2.3.0/gems/json-1.8.6/lib/json
    
    the code of the file until where you have to start completion: require 'ostruct'

module JSON
  class GenericObject < OpenStruct
    class << self
      alias [] new

      def json_creatable?
        @json_creatable
      end

      attr_writer :json_creatable

      def json_create(data)
        data = data.dup
        data.de
    
      def from_hash(object)
        case
        when object.respond_to?(:to_hash)
          result = new
          object.to_hash.each do |key, value|
            result[key] = from_hash(value)
          end
          result
        when object.respond_to?(:to_ary)
          object.to_ary.map { |a| from_hash(a) }
        else
          object
        end
