Exactly. It's a (at this point, unofficial) Swift feature called "function builders." The types end up being the same, because the conditionals are represented as wrapper types.

So

    if count == 0 {
      EmptyView()
    } else {
      Text("\(count)")
    }

would result in a type something like `Conditional<EmptyView, Text>`.
