What about:

You'll also note that there's a semicolon after the closing brace. That's because async() treats the following block as an anonymous subroutine, so the semicolon is necessary.

and:

threads->list() returns a list of thread objects, one for each thread that's currently running and not detached. Handy for a number of things, including cleaning up at the end of your program (from the main Perl thread, of course): 
    # Loop through all the threads
    foreach my $thr (threads->list()) {
        $thr->join();
    }

Is there any difference between threads->create() and async {...}?
