 I have a list of elements-  and for every element in the

element or the next one, as the case might be, how do I tell
perl to look at the previous element?
I like:

for (my $i = 1; $i < @list; $i++) {          # skipping index 0
        # in here, current is $list[$i]
        # and previous is $list[ $i - 1 ]
}
