Using Lists in FDs

Lists of objects are not a primitive type in FUF. The reason is that a list of FDs is not a legal FD. Lists are however very useful in grammatical description, when dealing with subcategorization or conjunction. FUF therefore contains some built-in support for the expression and manipulation of lists. The issue of list manipulation is further developed in Appendix , where list processing is used as an example showing the expressive power of FUF as a programming language.

This chapter explains how and when to use lists in FUF and describes the FUF facilities easing the use of lists.
