// Okay, here's something I really like from Kotlin & Swift, they're called Optionals (or Nullable)
// var coolThing: Bool?
// this means that that variable may be one of three values, null, true, or false.

// PHP has had this forever you might say
// $cool_thing = null
// That var could become a string, int, bool, whatever you'd like! But here lies the intersection where
// the typed world can help PHP, I think.
