Excellent info, Hartmut. Anyway, it doesn't bother me that they are
Wave-specific numbers, because that's the point, isn't it? You wouldn't
use const_string<> as a wholesale replacement for std::string<>, but if
you choose it in an appropriate application, you *can* realize up to
100% performance improvement. The fact that this is demonstrated in
Wave, and not an artificial benchmark makes it a very valuable test
point, in my opinion.
