I hate null. More specifically I hate NullPointerExceptions(NPEs). Scala has an alternative, but let me explain why I hate NPEs. They're like evil, sneaky muppets. Remember the Martians on Sesame Street? They'd ask each other if a phone was a cow and then say "nope, nope, nope, nope." To my eye, NPE looks a lot like "NoPE."
