Hi. Why function f below doesn't compile, while h does? Is it because of @kotlin.internal.InlineOnly annotation on let?

inline fun g(block: () -> Unit) = block()

    fun f(): Int {
        g {
            return 123
        }
    } // Error: A 'return' expression is required...

    fun h(): Int {
        null.let {
            return 123
        }
    }
