Using .tupled method when companion object is in class

I am in the process of migrating from Slick to Slick 2, and in Slick 2 you are meant to use the tupled method when projecting onto a case class (as shown here http://slick.typesafe.com/doc/2.0.0-RC1/migration.html)

The problem is when the case class has a companion object, i.e. if you have something like this

case class Person(firstName:String,lastName:String) {

}

Along with a companion object

object Person {
  def something = "rawr"
}

In the same scope, the tupled method no longer works, because its trying to run tupled on the object, instead of the case class.

Is there a way to retrieve the case class of Person rather than the object, so you can call tupled properly?

You can also write

(Person.apply _).tupled

to avoid repeating the types.
