A modern programming language that makes developers happier.

kotlinlang

I saw that the library supports
```<http://Dispatchers.IO|Dispatchers.IO> {
    println("Foo")
} ```
which is the same as
```withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
    println("Foo")
}```
Any idea why there are multiple ways to do it, and which one is preferred?

Huh! I never knew that. A bit of digging reveals this thread: <https://github.com/Kotlin/kotlinx.coroutines/issues/428>

I don't love that there are two ways to do the same thing :disappointed: I think I'll stick to `withContext`

Ahah it's really weird to read about the Coroutines design from _before_ structured concurrency.

is this from kotlin 2? The first option doesn’t work for me :thinking_face:

It's not tied to Kotlin version. it's an invoke operator in the kotlinx.coroutines library

No, it's old. IDEA doesn't import it by default though, it's `kotlinx.coroutines.import` if you want to try it out.

(or, spell it out entirely:)
```Dispatchers.IO.invoke {
    …
}```

This did the tricky! I kinda like it :eyes:
