yeah, good point. i actually almost wrote it as my @tags = grep {defined $_} map { ... } @files; (though i like the ? $1 : () much better).. left it out because, in theory, it should never not match, and if it does fail to match, perhaps (no clue if he does or not) OP wants to trap those cases ... 
foreach my $tag (@tags){
  die "found a blank" unless defined $tag;
  ....
}

(though i guess in that case you can't, very easily, tie the failing tag back to an offending file ... hm.)
