[Development] Regular expression libraries for QRegExp (what about "tre")

[Francesco Riosa]

reading these two blogs:
http://blog.rburchell.com/2011/12/why-i-avoid-qregexp-in-qt-4-and-so.html
http://blogs.kde.org/node/4510 (Regexp library benchmarks...)

I've learned of the TRE library (http://laurikari.net/tre/about/) it
has interesting functionality like fuzzy matching and seem to have all
what you need except for named matches (?name: bla bla)

I've tryed to compile it and it's very small.

Licensed "As is"

what does it miss for be elected in qt5 inclusion?

just out of curiosity
