Hi Monks, I just scratched my head for a good chunk of my time resolving an issue which boils down to this: 
use JSON;

$params->{timeout} = 2000;
$body->{"timeout"} = (defined $params->{timeout}?$params->{timeout} : 
+3000);
print "$body->{timeout}\n"; #<-----suspect line
my $body_string = to_json($body);
print "$body_string";

In the above code, the mere printing of the hash value adds double quotes to the timeout value in the json as shown in the output. 
Output: 
2000
{"timeout":"2000"}

Now if you remove the "suspect line" from the above code: 
use JSON;

$params->{timeout} = 2000;
$body->{"timeout"} = (defined $params->{timeout}?$params->{timeout} : 
+3000);
my $body_string = to_json($body);
print "$body_string";

[download]
Output: 
{"timeout":2000}

In the second output, the value 2000 wasn't wrapped in quotes. I find it really peculiar as to why the mere printing of the hash value changes the behavior of the output??
