I like hash slices:

    ($one, $two, $three) = @hash{ qw/aaa bbb ccc/ };

Sadly, this doesn't work as an lvalue:

    @hash{ qw/aaa bbb ccc/ } = ($one, $two, $three);        # WRONG

But this does:

    push @values, reverse @keys;
    $hash{ $values[$#values - $_] } = $values[$_] for 0 .. @values / 2 - 1;
    $#values /= 2;
