I wish more languages treated null like objective-c. Where if a method is called on a null object, nothing happens and the method returns null. In user land a 'null bug' in objective-c often results in a feature not responding, as opposed to the entire app crashing. It's a much better user experience, and I can write code less paranoid about null values as well.
