> Futures was stabilized before the async syntax, so this used to be the only way you could do it. While that's technically true (std::future was in 1.36 and async/await syntax was in 1.39), that's a very short timespan of only a few months. You are probably referring to the multiple years where futures only existed as addon libraries where their design was iterated on before the final design of std::future was settled on.
