 ### Arrays
 
-One thing about arrays to note is that they don't implement `Iterator.`. That means that if you have an array, you can't use `for`. But you can use methods like `.iter()` on them. Or you can use `&` to get a slice. Actually, the compiler will tell you exactly that if you try to use `for`:
+In the past (before Rust 1.53), arrays didn't implement `Iterator` and you needed to use methods like `.iter()` on them in for `loops`. (People also used `&` to get a slice in `for` loops). So this didn't work in the past:
 
 ```rust
 fn main() {
-    // ⚠️
     let my_cities = ["Beirut", "Tel Aviv", "Nicosia"];
 
     for city in my_cities {
