still nice tho.
Why not [1]?
[1] typeof(null) alwaysReturnNull() { ... }

Yeah nice, that works instead of auto.
That reminds me of the discussion about TBottom.
You see what surprises me here is that we cannot express the
special type that is `TypeNull` and that can only have one value
(`null`) so instead we have to use `auto` or `typeof(null)`.
Making this type public would make the logic more clear: when
`null` is used it's not a value but rather a value of a type that
is convertible to all pointers or reference types.
