 Function calls may sometimes result in ambiguities about receiver or referent.
 See [UFCS](#unambiguous-function-call-syntax) for how to resolve this.
 
-### Unambiguous Function Call Syntax
+### Unambiguous Function Call Syntax (UFCS)
 
 Several situations often occur which result in ambiguities about the receiver or
 referent of method or associated function calls. These situations may include:
 
 * Multiple in-scope traits define the same method for the same types
 * Auto-`deref` is undesirable; for example, distinguishing between methods on a
-  smart pointer itself and the pointer's referent.
-* Methods which take no arguments and return properties of a type, like
-  `SizeOf::size_of()`
+  smart pointer itself and the pointer's referent
+* Methods which take no arguments, like `default()`, and return properties of a
+  type, like `size_of()`
 
 The programmer may unambiguously refer to their desired method or function using
