 # The "nullable pointer optimization"
 
 Certain types are defined to not be `null`. This includes references (`&T`,
-`&mut T`), boxes (`Box<T>`), and function pointers (`extern "abi" fn()`).

 As a special case, a generic `enum` that contains exactly two variants, one of
 which contains no data and the other containing a single field, is eligible
 for the "nullable pointer optimization". When such an enum is instantiated
