Comment 2 Jan Kaluža 2011-02-07 14:17:26 UTC 
I'm not sure it will be possible to improve Perl recognition significantly, because Perl doesn't have so unique syntax in comparison with other languages.

The only thing I can probably do is to check if the file ends with "1;", because that's what usually perl headers do, but I don't believe it would be accepted by upstream.

I'll keep it open for a while and be thinking more about it.
Comment 3 Jan Kaluža 2011-03-22 10:39:04 UTC 
After some discussions with people who know Perl better than me I think there's no way how to significantly improve File Perl patterns and don't break detection of other scripting languages. Closing this as WONTFIX.
