http://stackoverflow.com/questions/3508077/how-to-define-type-disjunction-union-types#comment8603587_6883076

Example: 

  1. scala> import sclib.util.union._
scala> def f[A: (Int Or String)#Check](a: A): Int = a match {
     |   case i: Int => i
     |   case s: String => s.length
     | }
scala> f(5)
res0: Int = 5
scala> f("hey")
res1: Int = 3
// this throws a compiler error:
scala> f(5L)
