 This error occurs when you defined methods or associated functions with same
 name.
 
-For example, in the following code:
+Erroneous code example:
 
 ```compile_fail,E0592
 struct Foo;
 
+impl Foo {
+    fn bar() {} // previous definition here

+impl Foo {
+    fn bar() {} // duplicate definition here

 impl Foo {

 }
 
 impl Foo {
-    fn bar() {}
