In fact, playing with your solution, I can 'simplify' it further

printf $_ ? '%+4d' : '%4d', $_ for @nums;

But that's starting to look like golf...

    Did someone mention golf:) 

    printf $_ ? '%+4d' : '   0', $_ for -4 .. +4;
  -4  -3  -2  -1   0  +1  +2  +3  +4

    Actually it doesn't shorten the code any, but it maybe saves a few microseconds in parsing, both by the computer and the human being. Maybe?
