[plt-scheme] self-referential data structures

Chapper 9 of htdp describes lists which is a self-referential data structure
used to process data of arbitrary size.I was wondering the concept of
self-referential data structure limited to the functional paradigm or we can
use self-referential ds in imperative languages to process data of arbitrary
size.Someone please shed some light on this concept.
