## 3.4.4.1.1.1 Examples of Data-directed Destructuring by Lambda Lists

An example pattern is

`(a b c)`

which destructures a list of three elements. The variable `a` is assigned to the first element, `b` to the second, etc. A more complex example is

`((first . rest) . more)`

The important features of data-directed destructuring are its syntactic simplicity and the ability to extend it to lambda-list-directed destructuring.
