$"
This is like $, except that it applies to array and slice values
interpolated into a double-quoted string (or similar interpreted string).
Default is a space. (Mnemonic: obvious, I think.)

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";

__END__

Could someone tell me what $" is?
