 Thin pointers are "simple" pointers: they are purely a reference to a memory
 address.
 
-Fat pointers are pointers referencing Dynamically Sized Types (also called DST).

+Fat pointers are pointers referencing Dynamically Sized Types (also called

 To fix this error, don't try to cast directly between thin and fat pointers.
