+An assignment operator was used on a non-place expression.

 The left-hand side of an assignment operator must be a place expression. A
 place expression represents a memory location and can be a variable (with
 optional namespacing), a dereference, an indexing expression or a field

-Now, we can go further. Here are some erroneous code examples:
-
-```compile_fail,E0070
-struct SomeStruct {
-    x: i32,
-    y: i32
-}
-
-const SOME_CONST : i32 = 12;
-
-fn some_other_func() {}
-
-fn some_function() {
-    SOME_CONST = 14; // error : a constant value cannot be changed!
-    1 = 3; // error : 1 isn't a valid place!
-    some_other_func() = 4; // error : we cannot assign value to a function!
-    SomeStruct.x = 12; // error : SomeStruct a structure name but it is used
-                       // like a variable!
-}
-```

 And now let's give working examples:
 
 ```
 struct SomeStruct {
     x: i32,
-    y: i32
+    y: i32,
 }
-let mut s = SomeStruct {x: 0, y: 0};
+let mut s = SomeStruct { x: 0, y: 0 };
 
 s.x = 3; // that's good !
