I didn't even realize that Boost catered to it although I should have since
I have dealt with Regex++ enough. OK, if you allow end-users to build parts
of Boost without exception handling, I guess you can allow end-users to
build parts of Boost without RTTI support. I admit that if I were a Boost
library implementor, I would find such limitations on my natural use of C++
annoying.
