Using .tupled method when companion object is in class

You can also write

(Person.apply _).tupled

to avoid repeating the types.

One workaround is define a companion object as follows:

object Person extends((String,String) => Person) {
    ...
}

See. https://groups.google.com/d/msg/scala-user/jyWBMz5Qslw/Bryv4ftzRLgJ

This is very similar to what Alexey Romanov said, but in order to avoid lifting apply whenever you need tupled, we just add it to our companion objects.

object Person {
  def something = "rawr"
  def tupled = (Person.apply _).tupled
}

Now you can call Person.tupled just like you would have if it didn't have a companion object.
