 As can be seen, walking the Tangle is unnecessarily explicit.
 
-To address this issue we suggest a design that makes use of Rust's zero-cost approach to abstraction to transparently manipulate the Tangle using guard/reference types and the `Deref` trait.
+To address this issue we suggest a design that makes use of Rust's zero-cost approach to abstraction to transparently manipulate the Tangle using guard/reference types and the `Deref` trait. The `Deref` trait permits a type to dereference to another, thereby allowing one to call the methods of the inner type on the wrapper type.
 
 The equivalent code using the proposed API abstraction:
