Current example is not compiling:

import scala.reflect.{ClassTag, TypeTest}

val tt: TypeTest[Any, String] =
  new TypeTest[Any, String]:
    def unapply(s: Any): Option[s.type & String] = s match
      case s: String => Some(s) // compiler error Found: (s : String) Required: (s² : Any) & String
      case _ => None
