 There's a shorthand for initializing each element of an array to the same
 value. In this example, each element of `a` will be initialized to `0i`:
 
 ```{rust}
-let a = [0i, ..20]; // a: [int, ..20]

+Arrays have type `[T; N]`. We'll talk about this `T` notation later, when we
 cover generics.
 
 You can get the number of elements in an array `a` with `a.len()`, and use
