Re: [boost] Variadic append for std::string

Sorry to chime in so late in the discussion.

What about a syntax similar to this?

int main() { auto s = join("Hello ", ", World.", " The hex for ", 58, " is ", std::hex, 58); std::cout << s << std::endl;

s = join(separator(" : "), "a", "b", std::hex, 200 , std::quoted("banana")); std::cout << s << std::endl;

}

Which would produce the following output:

Hello , World. The hex for 58 is 3a a : b : c8 : “banana"

The syntax is fine but it's missing an appending variant, like append(s, "A", "B", 42); This variant is important as it (also) allows you to reuse existing storage.
