如何连接 std: : string 和 int？

Question

I thought this would be really simple but it's presenting some difficulties. If I have

std::string name = "John";
int age = 21;

How do I combine them to get a single string "John21"?

Common Answer: itoa()

This is bad. itoa is non-standard, as pointed out here.
