如何模式匹配大型Scala案例类？

case class Person(name: String, age: Int, address: Address)
case class Address(street: String, city: String, country: String)

def matchPerson(person: Person): String = person match {
  case Person("Alice", _, _) => "This is Alice"
  case Person(name, age, Address(_, "London", _)) => s"$name is $age years old and lives in London"
  case Person(name, _, _) => s"$name is a person"
  case _ => "Unknown person"
}

val person1 = Person("Alice", 25, Address("123 Main St", "London", "UK"))
val person2 = Person("Bob", 30, Address("456 Park Ave", "New York", "USA"))

println(matchPerson(person1)) // 输出："This is Alice"
println(matchPerson(person2)) // 输出："Bob is 30 years old and lives in New York"
