+The `Sized` trait was implemented explicitly.
+
+Erroneous code example:
+
+```compile_fail,E0322
+struct Foo;
+
+impl Sized for Foo {} // error!
+```
+
+The `Sized` trait is a special trait built-in to the compiler for types with a
+constant size known at compile-time. This trait is automatically implemented
+for types as needed by the compiler, and it is currently disallowed to
+explicitly implement it for a type.
