Implicit conversion of `Array[_]` failed

[liufengyun]

The code compiles in Scalac, but fails in Dotty. Both candidates Predef.genericWrapArray and Predef.genericArrayOps are found, but disqualified due to type inference error.

class T {
  def foo(any: AnyRef): Unit = {
    any.asInstanceOf[Array[_]].iterator
  }
}
