Too bad that 1.0 will ship without something like Scala Future's. Now you can only have a similar functionality with CompletableStage. It would've been way better to actually have a similar implementation than scala.Future. I mean they wouldn't need Quasar, Akka for basic stuff. However currently you need to stick to Java pendants.<p>Kotlin has some great things, but overall I still prefer Scala over Kotlin for anything not Android related.<p>I mean what I would've loved in 1.0:<p><pre><code> - specify Bytecode Level output 6, 7, 8, (9)
- Futures
- Macros (Big one especially for SQL Libraries really helpful)
- Buildsystem supported by Jetbrains.
- Support for all major Java Build Systems directly by Jetbrains
</code></pre>
However at the moment, kotlin feels like "here we developed a language which we will use internally and we will do the stuff we need, for everything else, do what you please", while most languages do this, the newer ones actually coming with more stuff, ie. rust has a package manager, a build system (it only lacks libraries, where kotlin wouldn't suffer, thanks to java), golang which has also something like a package manager and a build system and a rich library which has great support for "threading".<p>i mean on kotlin you could use maven or gradle. however maven is like:
<dosomething></dosomething> ugliness.
and gradle is okai, but it feels wierd sometimes especially since code highlighting in intellij always feels broken.<p>currently I'm way more looking forward at jetbrains c# project than on kotlin, kotlin needs to evolve and get some libraries for major stuff.
(btw. i'm not totally against kotlin, however I thought 1.0 will bring a little bit more to the table, which actually has more than just "faster" compile times than scala, the jvm is rich and there a lot of great languages built on top of it (even python, ruby, js works on it))<p>Edit Actually this author also has a good point about the good and the bad: <a href="http://natpryce.com/articles/000815.html" rel="nofollow">http://natpryce.com/articles/000815.html</a>
