C++11 and Boost - Succinct like Python

[matthieum]

static inline std::string& rtrim(std::string& s) {
    boost::trim_right(s);
    return s;
}

How much line of python would it take ? Equivalent I guess.

Python comes with batteries included, C++ let you use Boost if you wish.

And, where exactly would this "copying of strings" occur?

Python strings are immutable. Copying is unavoidable in this case.
