typeof(null) has quite a few interesting properties. It's the closest 
type to the bottom of all types (we don't have an actual bottom type), 
and it subtypes many other types as mentioned.

Introducing yet another type works against that nice uniformity and is 
yet another arbitrary little thing that people who learn the language 
would need to know about.
