I've talked to many, many people about RPerl over the last year. I've been asked all of the FAQ questions multiple times.

I'm sorry if that doesn't answer your question, I'm a little confused by what you were asking me?

[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 ;)
[Corion]: This is because Filter::Simple does some string-trickery, replacing all string literals with "quoted packed numbers"
[Corion]: I fear this might be a bug in the RE engine, but if it is a bug, even fixing won't help me because I need Filter::Simple for Filter::signatures , which provides signatures as a backwards compatibility feature for Perl <5.22 - and these ...
[Corion]: ... won't get a fix anyway ;) My plan B is to encode the string placeholders avoiding \r and \n
