Sweet Zombie NullFuckingPointerException...
New Rule: When creating an API (I'm looking at you, Java), designers must include a boolean flag in the parameter list of any method which throws a NullPointerException.
If TRUE, this means that a NULL result is non-trivial and the method should therefore THROW an NPE.
If set to FALSE, this means that NULL is completely f*cking trivial so whenever there's a NULL result, just instantiate a new instance of the return type and return that, 'cause that's what was gonna happen in the catch block of the NPE anyways.
