Fair enough. I defer to both of you.

I agree, though it may seem counterintuitive at first. () is a value of unit
type that exists here to satisfy the sema’s requirements that all branches are
destructive, productive or defer to another productive branch.

Well, unless I'm mistaken, `()` here is a value. I can replace it with `3`
and the compiler emits a warning about unused results. I'm guessing that
since () is a value of type Void, the warning about unused results isn't
triggered.
While it's true that `Void` causes an error, I can write `Void()` i
