Is there a way to implement analog of Python's 'separator'.join() in C++?

Question

All I\'ve found is boost::algorithm::string::join. However, it seems like overkill to use Boost only for join. So maybe there are some time-tested recipes?

Here is another version that I find more handy to use:

std::string join(std::initializer_list initList, const std::string& separator = "\\")
{
    std::string s;
    for(const auto& i : initList)
    {
        if(s.empty())
        {
            s = i;
        }
        else
        {
            s += separator + i;
        }
    }

    return s;
}

You can then call it this way:

join({"C:", "Program Files", "..."});
