description: >
  Enable fast path for JSON.stringify() serialization.  The fast path is used
  when there is no "replacer" argument.  Indent argument and JX/JC format is
  supported since Duktape 1.4.0.  The fast path increases code footprint by
  roughly 1.5 kB but is up to 4-5x faster than the slow path.

  Current limitation: assumes "long long" type exists (and covers duk_int64_t
  range) and that sprintf() format string "%lld" works for "long long".
