Hi monks!
I have an array and want to do something on every two succeding elements (its already sorted by a fancy sortfunction) At this moment I use the following ugly code

my $oldelem=0  # which cannot occur. 
foreach $elem (@elements) {
    do_something_with($oldelem,$elem) 
        unless $oldelem==0;
    $oldelem=$elem;
}

Is there any better way to do it?

Is there any way, to do this for n elements instead of two?

Regards...
