* serialization.
* @param {?boolean=} opt_useUnsafeParsing Whether to use goog.json.unsafeParse
* for parsing. Safe parsing is very slow on large strings. On the other
* hand, unsafe parsing uses eval() without checking whether the string is
* valid, so it should only be used if you trust the source of the string.
