Var-arg method accepting only primitives or Seq[primitive]

How to create method, that will be accepting only primitives or their Seq's? Moreover it should be var-arg.

def method(args: Param*)

where args are for example

method(1: Int, 1l: Long, "1": String, Seq(1, 3, 7))

the second condition is that it can NOT accept value classes

Define Param like this:

sealed abstract class Param

object Param {
  implicit final class IntParam(val x: Int) extends Param
  implicit final class StringParam(val x: String) extends Param
  ...
  implicit final class SeqParam(val seq: Seq[Param]) extends Param
}
