scala> val d: Validation[String, Int] = 12.success
d: scalaz.Validation[String,Int] = Success(12)

scala> val e: Validation[String, String] = "ghosh".success
e: scalaz.Validation[String,String] = Success(ghosh)

scala> (d, e)
res18: (scalaz.Validation[String,Int], scalaz.Validation[String,String]) = (Success(12),Success(ghosh))

// I want to get Validation[String, (Int, Int)] out of this. The closest I could get is ..

scala> (d, e).sequence[({type λ[α]=Validation[java.lang.String, α]})#λ, String]
res38: scalaz.Validation[java.lang.String,(scalaz.Validation[String,Int], String)] = Success((Success(12),ghosh))

Thanks .. I was tricked into thinking in terms of sequence .. Alexey also suggested the same on the ML ..
