I was wondering why:

print "$one, $two\n";

Try:

my( $one, $two ) = @{ ($q->dequeue_dontwait)[0] };


The @{ } forces scalar context within the {}, so it is trying to dereference "1" (being the number of elements returned). Which you will see if you add:

use strict;

(which you should probably always do anyway).


I could probably change the dequeuexxx routines of Thread::Queue::Any to return the first element only if called in a scalar context. However, this would add a significant amount of overhead in otherwise very lean methods, so I'm a bit reluctant to do this.


Opinions anyone?
