A modern programming language that makes developers happier.

kotlinlang

And from the example:

```
inline class Name(val s: String) {
    val length: Int
        get() = s.length

    fun greet() {
        println("Hello, $s")
    }
}   
```

Would it not be preferred to use `inline val length...`?

Not really. HotSpot and r8 will inline the getter method.
We've measured unsigned arithmetics performance on some number crunching code (which called such small methods in a tight loop) against equivalent manual implementation. No difference, both on HotSpot and on Android with d8+r8.
