consing

Verb

cons (third-person singular simple present conses, present participle consing, simple past and past participle consed)

1. To obtain a list from a cons or a nesting of conses; to prepend an element to a list by forming a cons of that element and the list; to obtain a list from a smaller one by repeated application of such kind of prepending.
   • This version of length arises naturally from the recursive definition of a list: “a list is either the empty list or an element consed onto another list.”1992, Peter Norvig, Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp, Morgan Kaufmann, →ISBN, page 62
