was just poking around in kotlinx-coroutines. Saw
Copy code
/**
 * Returns the context of the current coroutine.
 */
@SinceKotlin("1.3")
@Suppress("WRONG_MODIFIER_TARGET")
@InlineOnly
public suspend inline val coroutineContext: CoroutineContext
    get() {
        throw NotImplementedError("Implemented as intrinsic")
    }
That is a wild bit of code. How does a
suspend inline val
exist in the language, and how is it that all it takes to make it work is to suppress the compiler warning that that’s not allowed?

the definition here is just to make the name and type available to the frontend; the compiler backend recognizes the intrinsic name and replaces it with an implementation that cannot be expressed in pure Kotlin
