Yes, SelfGOL breaks when tidied, but only because it uses a subroutine
named ";\n" (literal semicolon, literal newline). Not, I suspect,
something perltidy should really be expected to cope with. ;-)

There *are*, however, a few places where whitespace is significant in
"normal" Perl code too. We had the example on this list just last

    print $x + $y;


   print $x +$y;
