  NSLog( @"%@\n", jsonObj )
  
  CfDictionaryRef    dict = @{ @"blue": @[@1, @2], @"ocean": @"water"}
  CFDataRef      jsonData = fn JSONSerializationDataWithJSONObject( dict, 0, @err )
  if err then NSLog( @"%@", fn ErrorLocalizedDescription( err ) )
  CFStringRef jsonString2 = fn StringWithData( jsonData, NSUTF8StringEncoding )
  NSLog( @"%@\n", jsonString2 )
