Dear Monks,

I'm having some trouble with Thread::Queue::Any. I managed to reduce the problem to the following : 

############# code starts here #############
use strict;

use threads;
use threads::shared;
use Thread::Queue::Any;

our $| = 1;

my $QUEUE : shared;
my $TERMINATE : shared = 0;
my $THREAD;

sub TimeThread {
  while (!$TERMINATE) {
      sleep 1;
      $QUEUE->enqueue(scalar(localtime()));
  }
}


$SIG{TERM} = sub {
  $TERMINATE=1;
  $THREAD->join;
  exit;
};

$QUEUE=Thread::Queue::Any->new;

$THREAD=threads->new(\&TimeThread);

while (1) {
  sleep 1;
  if ($QUEUE->pending) {

    ######## This is really weird! ########
    my $time = $QUEUE->dequeue; print $time; ### NOT OK
    #print $QUEUE->dequeue;                  ### OK.
  }
}
############# code ends here ##################

If I run the code as is, the output reads:

1111 ...

and so on.

Now if I replace line no. 37 with: 

    print $QUEUE->dequeue;

I get the expected result, namely nicely formatted localtime()s.

What am I doing wrong ?

Thank you,

R.
