Still, does it really seem like a good idea to do what the designers of the STL wanted to explicitly disallow...
I don't believe any such intent was ever expressed by the standard committee. It's true that they explicitly avoided virtual functions in the standard library -- iostreams excepted. It's really Scott Meyers advice that drives the 'never inherit' from a base w/o a virtual destructor. As much as I generally agree with that advice the 'stateless' functional extension is a useful and portable technique in my experience.
Why not define additional functionality externally? (I believe there was once a library in the Boost review queue called string_algo, or similar). This would be a better design choice, IMO.
Ah, string_algo is part of boost and super_string uses it in the implementation just like it uses boost.regex and boost.format. It might be informative for you to go back and read the earlier email thread. http://lists.boost.org/Archives/boost/2006/07/107087.php Jeff
