The question is malformed because it contains a term that cannot be evaluated.

I see the question this way:

   fn is_n_prime_whether_or_not_God_exists()
       if (is_prime(3) && is_prime(5)) { // early return 
            return true;
       } else { 
            return three_if_God_exists_five_otherwise(); 
       }
   }

Even if evaluating that would make no difference?

[denton-scratch]

"God" has some unique properties. One of those might be that God neither exists nor doesn't exist. If God has this property of 'neitherism', then the value of n is undefined. Neitherism has been attributed to many religious entities.

To answer a question, you first have to be able to parse the question.

That's the problem with side effects: you don't know if they make a difference until you evaluate them. And "God" is about the biggest imaginable side effect.

Well, the compiler says undefined behavior and optimizes it away :D
