What is a readable function?
Ignoring that part, you can always rewrite something like:
(while condition ...)
as
(iterate loop ()
(when condition ... (loop)))
where iterate is defined as:
(defmacro iterate (name args &rest body)
`(labels ((,name ,(mapcar 'first args) ,@body))
(,name ,@(mapcar 'second args))))
Is that what you meant?
