The philosophy behind the STL would suggest accessing containers
through their iterators. Something like

std::cout << "new path is "
          << Foo(v.begin(), v.end())
          << "\n";

would not be too bad (and it would be even better if it were called
something besides "Foo"). This would be very general, while
remaining quite readble, I think.

Delimiters could be set using optional parameters, among other
methods.

std::cout << "new path is "
          << Foo(v.begin(), v.end(), "[", ",", "]")
          << "\n";
