I just came across a piece of code that reduces to: 

$n = 10; 
while( $n ){ 
    print $n--; 
}
continue{ 
    sleep 1;
}

[download]

Which as far as I can see is identical in behaviour to: 

$n = 10; 
while( $n ){ 
    print $n--; 
    sleep 1 
}

[download]

Is there any benefit to the first form?

I can't ever remember having used it. Do you? Could you post an example or two of its real world uses?
