Introduction

Method overloading sucks in Scala because it detracts from your flexibility. An implicit conversion is a feature of Scala that let's the compiler look up how to convert objects between types at compile time.

Let's say I define a method with the following signature:

def doSomething( action: Action )

Somewhere else in the code I write:

bstract class Prize {
  def * (num: Int): List[Prize] = {
    if (num == 0) Nil
    else {
      import collection.mutable.ListBuffer
      val l = new ListBuffer[Prize]
      for (i <- 1 to num)
        l += this
      l.toList
    }

(function() {
    var lastTime = 0;
    var vendors = ['ms', 'moz', 'webkit', 'o'];
    for (var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) {
        window.requestAnimationFrame = window[vendors[x] + 'RequestAnimationFrame'];
        window.cancelAnimationFrame =
        window[vendors[x] + 'CancelAnimationFrame'] || window[vendors[x] + 'CancelRequestAnimationFrame'];
    }

    if (!window.requestAnimationFrame) window.requestAnimationFrame = function(callback, element) {
