Does vector emplace compile faster than push_back?
<p>While <code>emplace</code> can have run-time benefits, <a href="https://stackoverflow.com/a/26953649/3758484">this answer</a> suggests it can also speed up compilation. <a href="https://stackoverflow.com/questions/26953394/initializing-a-vector-of-structs-takes-large-compile-time/26953649#comment42447644_26953649">This fellow</a> agrees.</p>

<p>Why is that?</p>
