[...] Just wanted to mention here, that I've used const_string as a plug in replacement for std::string for my Wave library and succeeded without any further problems. Moreover, the const_string class gave a perfomance boost of about 20% if compared to the flex_string and about 100% if compared to the std::string (I can provide the concrete numbers, if somebody is interested). But these numbers certainly very specific to Wave and its applications.
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. Dave
