 * Stable msgpack extension type codes for built-in runtime value types.

 * These numbers are part of the wire format. Changing an existing code is a
 * breaking change that would invalidate all previously stored outputs. Treat
 * this file as append-only.
 *
 * Msgpackr reserves negative codes for MessagePack itself and 101-127 for its
 * own use. Codes 1-100 are available to built-in application values.
