Perl qr function usage
I'm not sure why I'm having so much trouble with this.
I think I'm really not understanding how this works.

I'm trying to store a regex in a variable for use later in a script.

Can someone tell me why this doesn't match???
Code:
#!/usr/bin/perl
#
#
#
$ticket=1212;

my $rx_ticket = qr/^\d{4}$/;

if ($ticket !~ /$rx_ticket/) {
        print "It matches\n";
}
else {
        print "No match\n";
}


print "Finished\n\n";
print "$ticket\n";

I expected it to match, but I get the following output:

Code:
$ ./ticket.pl
No match
Finished

1212

What am I not understanding here???
I'm sure it something simple.

Thanks

shishi_tkt_proxiable_p

shishi_tkt_proxiable_p(3)					      shishi						 shishi_tkt_proxiable_p(3)

NAME

       shishi_tkt_proxiable_p - API function

SYNOPSIS

       #include <shishi.h>

       int shishi_tkt_proxiable_p(Shishi_tkt * tkt);

ARGUMENTS

       Shishi_tkt * tkt
		   input variable with ticket info.

DESCRIPTION

       Determine if ticket is proxiable.

       The PROXIABLE flag in a ticket is normally only interpreted by the ticket-granting service. It can be ignored by application servers.  When
       set, this flag tells the ticket-granting server that it is OK to issue a new ticket (but not a ticket-granting  ticket)	with  a  different
       network	address  based	on this ticket. This flag is set if requested by the client on initial authentication. By default, the client will
       request that it be set when requesting a ticket-granting ticket, and reset when requesting any other ticket.

RETURN VALUE

       Returns non-0 iff proxiable flag is set in ticket.
