sub ranger {
    my ($arr, $r, $sr) = @_;

    # Unneeded, plus it doesn't work.
    #local $[ = $r->[0];

    $sr->[$_] -= $r->[0] for 0 .. 1;

    ($sr->[0] < $sr->[1])
        ? @{$arr}[$sr->[0] .. $sr->[1]]
        : reverse( @{$arr}[$sr->[1] .. $sr->[0]] );
}

Update: Upon actually trying the above code, I found it doesn't work like I thought it would. However, I found that I didn't need $[ at all.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
