I mean, you can do that (and it kight be useful if you want to seperate where the construction arguments are from where when the initialisation happens), but I don't understand why not just do it in init instead of build. It's not all that special, it's literally just a method that's called when you make an instance of the class, if you need to do it before you use the class, just make it happen when you make the class.
