Hi! I thought

suspend

lambdas could be used just like normal lambdas. Why then is this not allowed?:

fun main() {
    val f = suspend { i: Long ->
        delay(i)
    }

    runBlocking {
        f(1000L)
    }
}

You must specify the type in the declaration, not in the usage block

val f: suspend (Long) -> Unit = { i: Long ->
        delay(i)
    }

    runBlocking {
        f(1000L)
    }

Ahh, ok, so when using the

suspend

keyword together with a parameterised lambda, the variable needs to be annotated? Contrast with a normal lambda where this is perfectly fine:

val f = { l: Long ->
   Thread.sleep(l)
}
