A modern programming language that makes developers happier.

kotlinlang

Is there anyway I could get:
```
CompletableFuture&lt;List&lt;Person&gt;&gt;
```
from
```
List&lt;CompletableFuture&lt;Person&gt;&gt;
```

I can't wrap my head around it :confused:

According to :stackoverflow: (<https://stackoverflow.com/questions/30025428/listfuture-to-futurelist-sequence>), you can use a function like this:
```
fun &lt;T&gt; List&lt;CompletableFuture&lt;T&gt;&gt;.unwrap(): CompletableFuture&lt;List&lt;T&gt;&gt; =
    CompletableFuture.allOf(*toTypedArray()).thenApply { map { it.join() } }
```

Basically, it creates a wrapper `CompletableFuture` that waits for all the others to finish, then unwraps each value into a list.

interesting.. thank you, hopefully the dispatcher will be happy with this
