How to do have constant values in a insert, so it doesn't have to be provided in the insert invokation?

	// It's a Table[(Int, Int, DATE)]
	def autoInc = compilationId ~ creationDate returning id into {
	case (tuple, id) => (id,tuple._1,tuple._2)
	}
	def autoInc2 = * returning id

	// this is the work around. I don't want use session here.
	def insertNewVersion(c:Compilation)(implicit session:Session) = autoInc.insert(c.id.get,newDate)._1

	// what i want - my very wrong attempt

auto increment insert in slick. There must be better way.

	def autoInc = * returning id.? into {
	case (Person(_, a, b,c ,d), id) => Person(id, a, b, c, d)
	}

	def autoInc2 = fullName ~ birthday ~ login ~ password returning id.? into {
	case (m, id) => Function.uncurried(((Person.apply _).curried(id))).tupled(m)
	}

This error occurs when trying to compile my source code with -Yrangepos. My source depends on Slick macro I will post the usage site below, links for the Slick source and the error.

	My Source:

	override def expr(n: Node, skipParens: Boolean = false) =
	n match {
	case Extract(n @ _*) =>
	val datePart = n(1).asInstanceOf[LiteralNode].value.asInstanceOf[String]
	b"""extract('${datePart}' from ${n(0)})"""
	case _ => super.expr(n, skipParens)
	}
