 | [Object map] properties holding values                | properties  |
 | [Object map] properties that hold [function pointers] |   methods   |
 
+When a property of an [object map] is called like a method function, and if it happens to hold
+a valid [function pointer] (perhaps defined via an [anonymous function]), then the call will be
+dispatched to the actual function with `this` binding to the [object map] itself.
 
 Examples
 --------
 
 ```rust
 // Define the object
-let obj = #{
-                data: 0,
-                increment: Fn("add"),       // when called, 'this' binds to 'obj'
-                update: Fn("update"),       // when called, 'this' binds to 'obj'
-                action: Fn("action")        // when called, 'this' binds to 'obj'
-           };
-
-// Define functions
-fn add(x)       { this.data += x; }         // update using 'this'
-fn update(x)    { this.data = x; }          // update using 'this'
-fn action()     { print(this.data); }       // access properties of 'this'
+let obj =
+     #{

+          action: || print(this.data)       // when called, 'this' binds to 'obj'

 // Use the object
