Re: A C++ Immutable String class
#6I guess I expected the whole point of an immutable string class would be to have O(1) copies. What does this buy you beyond 'const std::string'?

#7This defeats the purpose of std::string const s("Hello");
You specify that the place s is const, not the value it keeps. You can still do:
#include
#include
// not your code
void innocentF(std::string const& s) {
(const_cast(s)) += std::string(" I'm evil.");
}
// your code
int main() {
std::string const s("hello world.");
innocentF(s);
std::cout Re: A C++ Immutable String class
#8This defeats the purpose of std::string const s("Hello");
You specify that the place s is const, not the value it keeps. You can still do: #include #include // not your code void innocentF(std::string const& s) { (const_cast (s)) += std::string(" I'm evil."); } // your code int main() { std::string const s("hello world."); innocentF(s); std::cout
The point is that one shouldn't do it accidentally. When you're explicitly using const_cast, it is fine.

#9It's immutable but it defines swap? That seems.. odd.

immutable_string s("hello world.");
reinterpret_cast(s) += "I'm evil";
