Printing main method in Scala3(Dotty) gave value as Main$$$Lambda ... Why?

I wrote a code below in Scala .

object Main {
  def main(args: Array[String]): Unit = {
    println(main) 
  }
}

It gave output as : Main$$$Lambda$3/1543727556@3930015a Why is this value returned ?

Also, When I wrote a simple method like one below :

def wow(): Unit = {
  println(wow)
}

But it gives compilation error.
