// How to combine this method declaration....
def Given(name: String, body: Function2[Int, String, Unit]): Unit = {
  body.apply(5, "belly")
}

// ...and this method declaration to one polymorphic declaration...
def Given(name: String, body: Function1[String, Unit]): Unit = {
  body.apply("bob")
}

// ...that can be invoked like this...
Given("I have (\\d+) cukes in my (.*)", (cukes:Int, where:String) => {
  println("You have " + cukes + " cukes in your " + where)
})

// ...and this
Given("my name is (.*)", (name:String) => {
  println("Your name is " + name)
})
