cl: Loop Facility

 
 4.7 Loop Facility
 =================
 
 A common complaint with Lisp’s traditional looping constructs was that
 they were either too simple and limited, such as ‘dotimes’ or ‘while’,
 or too unreadable and obscure, like Common Lisp’s ‘do’ loop.
 
    To remedy this, Common Lisp added a construct called the “Loop
 Facility” or “‘loop’ macro”, with an easy-to-use but very powerful and
 expressive syntax.
