"Because it looks like a keyword in other languages. But in fact what it does it calls a function and passes it a lambda and this function is some later time executes this lambda."

repeat, launch, retry functions that look like

```launch {
  delay(200)
}```
can be re-written as

```val lambda: suspend Coroutine.() -&gt; Unit = { delay(200) }
launch(block = lambda)```
