Supposedly the more items you add to a dictionary in Swift (in assigning a variable with a fleshed-out dictionary) the longer the compiler will take, exponentially longer, to a ridiculous degree as there is a bug with type inference.

Type inference is the deduction of type based upon assignment. true might be a bool and 13 an int in C# when one assigns to a var variable. null cannot be an assignment to a var variable because there is no way to infer a type, you know?
