Latest JSON::Parse (mine is 0.40) has a warn_only() function which does supposedly not let program die but return undef. How do I use this feature? 
use JSON::Parse;
my $JP = JSON::Parse->new();
$JP->warn_only();
$JP->warn_only(1);

or even 
JSON::Parse->warn_only($JP, 'on');

it gives me: 
Usage: JSON::Parse::warn_only(parser, onoff)

[download]
or: 
JSON::Parse::warn_only: parser is not of type JSON::Parse

[download]
EDIT: note: the following does not complain but has no effect i can notice of. 
$j->warn_only(1);

Below is a perl snippet to demonstrate the issue: 
use strict;
use warnings;

use JSON::Parse 0.38;
use Data::Dumper;

my $j = JSON::Parse->new();
# no complain, no effect:
$j->warn_only(1);

# legal json:
my $pl = $j->run('{"k":"v"}');
print Dumper($pl);
print "I am not dead 1\n";

# illegal json, the following statement dies:
$pl = $j->run('illegal json');
print Dumper($pl);
print "I am not dead 2\n";

Results: 
$VAR1 = {
          'k' => 'v'
        };
I am not dead 1
JSON error at line 1, byte 1/12: blah blah blah at which point it has 
+died.
