in reply to Hello World in four languages... at the same time

If you enjoy this sort of thing, there's a really good article by Jérôme Quelin which describes how he wrote a program that is valid on four languages: Perl, C, Befunge, and BrainF*ck. Very interesting read on how to trick the different languages into either working with each others syntax or ignoring parts of the program. http://www.if.insa-lyon.fr/eleves/jquelin/quadri.html

[Discipulus]: good morning Corion!
[Corion]: I spent parts of yesterday digging into Filter::Simple to make it not change the line numbers of unfiltered code, but I think I need regex help (which will come in a SoPW I guess). I tried @lines = /((?:"...."|[^" \n]+)\n)/gs, but that matched on...
[Corion]: ... foo "\0\0\0\n" bar\n by matching the first \n instead of matching the four-bytes-in- double-quotes part
[Corion]: ... and I still don't understand why ;)
