#!/usr/bin/perl

use strict;
use warnings FATAL => 'all';
use feature qw(say);

use constant MY_CONSTANT => "42";

use Cpanel::JSON::XS;

say encode_json { value => MY_CONSTANT };

my $smth = 0 + MY_CONSTANT;

This output

{"value":42}

But I would like to see in the output json the same type of the variable that I've used when defining constant, so in this case I expect to see

{"value":"42"}
