Your Monkness,

I apparently don't understand a scoping or access issue with trying to access my main program's variable from the thread subroutine. I have:

use strict;
use Thread;

my $time : shared;
my $t = Thread->new(\&listener,\$time);

while (1) {
    $time = localtime;
    print $time,"\n";
    sleep 1;
}

sub listener {
    my $time_ref = shift;
    while (1) {
        {
            lock($$time_ref);
            print "\tThread time: [$time]\n";
            print "\tThread time: [$main::time]\n";
            print "\tThread time: [$$time_ref]\n";
        }
        sleep 3;
    }
}

Which prints out:

Wed Feb  9 08:06:02 2005
        Thread time: []
        Thread time: []
        Thread time: []
Wed Feb  9 08:06:03 2005
Wed Feb  9 08:06:04 2005
Wed Feb  9 08:06:05 2005
        Thread time: []
        Thread time: []
        Thread time: []
Wed Feb  9 08:06:06 2005

Indicating to me that the thread only sees the initial value like it has it's own copy. Is that right? How do I access the main threads $time var? Hmmmmm.
