Hi,

One frequently needs to append stuff to strings, but the standard way
(s += "A" + "B" + to_string(42)) isn't optimal due to temporaries.
A variadic append() for std::string seems like the obvious solution.
It could support string_view (boost and std), integers, maybe floats
but without formatting options..
It could even be extensible by calling append(s, t);

append(s, "A", "B", 42);

Would this be useful for the Boost String Algo lib?
