Could someone tell me what $" is?

$LIST_SEPARATOR
$" This is like $, except that it applies to array and slice val-

It's the string Perl uses to separate array values when expanded inside
a double-quoted string.
#!/usr/bin/perl
use strict;
use warnings;
my @array = qw( a b c );
$" = ', ';
print "@array\n";
