I understand it is strange to hit whitespace issues in Perl (where weirdness like my$   n = 1 is legal) but this seems sensible and, this part, not hairy; I'd be alarmed if it worked any differently. Only the print(list) and file handle stuff is surprising and Perl users learn those issues, I hope, pretty early. +4 looks, like -4, unambiguously signed. Maybe the negative reads more clearly since we're used to never seeing the positive.

print $n -4;
