Would anyone be interested in having a perl-like regex shortcut notation?

Something like this would fit in easily with Eric Niebler's xpressive library. In fact, I suggested it, but Eric said it was "too cute". Perhaps we should convene a focus group to discuss the subject. ;-)
In fact, you could use almost completely emulate perl syntax if you want to: string str = ...; sregex rex = ...; str ^= _s/rex/"c++ sux, perl rulz!!"/_g; It's certainly cute, and it would be an interesting exersice. It is also not particularly appealing to me, since the only reason I wrote a C++ regex engine in the first place was because I strongly disliked perl's syntax. And to me, it seems less like a domain-specific embeded language than like simply trying to write perl in C++ -- an endeavor of dubious value. There are many things I need to add to xpressive. This is far, far down the list, but if someone wanted to submit a patch to xpressive (including docs and tests!), I wouldn't be opposed to adding it (so long as it could be cleanly isolated in a nested namespace). -- Eric Niebler Boost Consulting www.boost-consulting.com
