如何在Kotlin中间接调用function

Question

Assume I have a mutableMap:假设我有一个 mutableMap：

val MM = mutableMapOf()

Now I define a function as a method for it:现在我定义一个 function 作为它的方法：

MM["testF"] = fun () {
  println("WOW")
}

Now I want to call it in another place:现在我想在另一个地方调用它：

val MMTF = MM["testF"] as Function<*>
MMTF() <-- NOT WORKING

Any help will be appreciated.任何帮助将不胜感激。

This code will print bar此代码将打印 bar

fun main() {
    val map = mutableMapOf<String, () -> Any>()
    map["foo"] = {
        println("bar")
    }
    run(map["foo"]!!)
}
