in reply to Array manipulation how to

Let me add one more:

  • rotate an array left/right
    • # rotate @array left
my $temp=shift @array;
push(@array,$temp);

# rotate @array right
my $temp=pop @array;
unshift(@array,$temp);

      And without an additional variable: 
      push @a, shift @a;
unshift @a, pop @a;

        would this work? 
        @_=@a; push, shift;
@_=@a; unshift, pop;

          No, as that doesn't modify @a.
