Is this a bug in the overload resolution:

@OptIn(ExperimentalTypeInference::class)
@OverloadResolutionByLambdaReturnType
fun foo(bar: () -> String): String {
    return bar()
}

fun foo(bar: () -> String?): String? {
    return bar()
}

fun main() {
    val present: String = "Hello"
    val missing: String? = null
    val a = foo { present } // Works
    val b = foo { missing } // Return type mismatch: expected 'String', actual 'String?'
}

I would expect a to be a String, and b to be a String? , but instead it just doesn't compile.
