In fact, 

$ perl -MData::Dumper -MJSON -wE 'print Dumper decode_json("[true]")'
$VAR1 = [
          bless( do{\(my $o = 1)}, 'JSON::PP::Boolean' )
        ];

Note that it returns the PP for all of JSON::PP, JSON::XS, and Cpanel::JSON::XS.
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
