 *************************** CAUTION **************************************
 *                                                                        *
 * INCOMPATIBLE CHANGE (JSON::XS version 2.90)                            *
 *                                                                        *
 * JSON.pm had patched JSON::XS::Boolean and JSON::PP::Boolean internally *
 * on loading time for making these modules inherit JSON::Boolean.        *
 * But since JSON::XS v3.0 it use Types::Serialiser as boolean class.     *
 * Then now JSON.pm breaks boolean classe overload features and           *
 * -support_by_pp if JSON::XS v3.0 or later is installed.                 *
 *                                                                        *
 * JSON::true and JSON::false returned JSON::Boolean objects.             *
 * For workaround, they return JSON::PP::Boolean objects in this version. *
 *                                                                        *
 *     isa_ok(JSON::true, 'JSON::PP::Boolean');                           *
 *                                                                        *
 * And it discards a feature:                                             *
 *                                                                        *
 *     ok(JSON::true eq 'true');                                          *
 *                                                                        *
 * In other word, JSON::PP::Boolean overload numeric only.                *
 *                                                                        *
 *     ok( JSON::true == 1 );                                             *
 *                                                                        *
