This doesn't appear to be a perl issue, but rather a Data::Dumper issue.

Why is Data::Dumper involved anyway? 

use Data::Dumper;
my $re_bad  = qr'@@([A-Z$#@_#]*) (?! [A-Za-z0-9$#@_] )'x;
print Dumper $re_bad;
print "\n\n\n";
print $re_bad;
__END__
$VAR1 = qr/(?x-ism:@@([A-Z$#@_#]*) (?! [A-Za-z0-9$#@_] ))/;



(?x-ism:@@([A-Z$#@_#]*) (?! [A-Za-z0-9$#@_] ))
