Well, the STL has a solution for that, but the header is, unfortunately,
underused IME.

    #include <iterator>

    std::copy(src.begin(), src.end(), std::back_inserter(dest));

That said, I do wish there were a "InsertIterator" concept or the like
which std::copy would require (and probably move the existing std::copy
to std::unsafe_copy if it's deemed required still).
