That's what I meant with the requirement of qr// being able to stringify any /u that it got (either explicitly or through a pragma that makes it default). I think it's straightforward. A certain set of character classes is defined to behave in one way under /a, and another under /u. I'd say the innermost defined one determines, so /foo(?a:\w)/u would match fool but not fooĊ. > > However, there's also a way to > Missing sentence ?

I initially announced it at the Dutch Perl Workshop and then lacked tuits to make it a release. I might release it in its current state this evening. It believe that although it's not thoroughly tested yet, it'll work well. -- Met vriendelijke groet, Kind regards, Korajn salutojn, Juerd Waalboer: Perl hacker <#####@juerd.nl> <http://juerd.nl/sig> Convolution: ICT solutions and consultancy <sales@convolution.nl> 1;
