 * Scalars are now dumped more consistently. Strings always have quotes, numbers never do.
   This should address discrepancies that arise when dumping a string of digits. Previously,
   the string would have been dumped either with "non-specific" tag notation (i.e. "!") or
   without quotes. Both result in an integer when parsed. Now if you want to dump a number
   as a string, convert it to a string before serializing.
