Wouldn't the flex_string be even more flexible if it accepted ranges in constructor, assignment etc. (same for fixed_string, const_string of course)

Then you could easily switch between different string types without the .c_str ()

template <class RangeT> flex_string(const RangeT& input, const A& a = A()) : Storage(a) { assign(begin(input), end(input)); }

That would take it away from std::basic_string, but I think it's an standard-allowed extension. Andrei
