For testing purposes, the easiest way to go is jitpack:

resolvers += "jitpack" at "https://jitpack.io"
libraryDependencies += "com.github.User" % "Repo" % "Tag"

// Define the general Arg type and companion object:
import language.higherKinds, language.implicitConversions, language.existentials
object Arg { implicit def toArg[Tc[_], T: Tc](t: T): Arg[T, Tc] = Arg(t, implicitly[Tc[T]]) }
case class Arg[T, Tc[_]](value: T, typeclass: Tc[T])

// Say, for example we have a typeclass for getting the length of something, with a few instances
trait Lengthable[T] { def length(t: T): Int }
implicit val intLength = new Lengthable[Int] { def length(i: Int) = 1 }
implicit val stringLength = new Lengthable[String] { def length(s: String) = s.length }
