Hi all,
I came over an interesting post in stackoverflow
It explains that in Java/C++ processing a sorted array is faster than an unsorted. Let's say you have an array @a, then. 
my $sum;
foreach my $x(@a) {
if($x>128) {
    $sum +=$x;
}
}

If @a is sorted, will it be faster than unsorted?
Similary if i have a condition: 
fun_a($x) && fun_b($x) &&.....&&fun_z($x)

[download]
and fun_z fails consistently, will fun_z be calculated at the beginning?
Thanks, David
