That begs the question: do we need Boost.Regex's interface? I'm not up to 
date on Boost.Regex's status as far as TR1, so maybe it's a done deal 
already. But it seems to me that xpressive has a broader application domain, 
and may be a better candidate?

I stopped using Boost.Regex after I invested the time to learn Spirit. Not 
that there was anything wrong with Boost.Regex. I just started to think in 
terms of Spirit grammars and functor parsers. My programming productivity 
seems to be bound by my memory limitations. So I try to utilize a learned 
technology as often as I can to keep up on the nuances of the tool.
