That all makes sense. I've only done a couple days of Rust, so my recollection is spotty. The shadowing makes sense because if a local variable was moved out, then you're not really shadowing it anymore. Is my understanding of that correct?

> do you mean that Rust's `self.` is implicit in Swift?

Swift's `self.` is implicit in Swift – in most contexts, to access a property the `self.` is not required. `self.name = "John"` and `name = "John"` are equivalent (assuming self is an object with a name property).

There are places where explicit `self.` is required though – when you want to differentiate between a shadowed local and a property (obviously), or when you're inside a closure (to make it clear that the closure is capturing self, not just capturing a reference to the property).
