How is the usage you shown faster than a growing push_back?
It's inlineable. And it doesn't check for a full buffer. The difference can be anything from not much to really much.
Can't push_back call reserve if it doesn't fit? That way push_back could still be inlineable. Or am I missing something?
But I don't like adding a growing push_back() unless we have a use-case.
The use-case seems obvious to me. A vector that can use stack-allocation for >90% of the cases for an application. As someone pointed out, signals2 uses one in a detail namespace.
Is that use case different from the above?
I don't think so. But it is quite common it seems.
