Package ix.util.lisp Description

List-processing utilities.

The list classes in this package were first implemented before the Java collection classes were defined, although they have now been brought into the collection framework. They have been retained because they offer some features that are not provided by any of the java.util package collections and because they are useful for processing data that has a Lisp-like syntax.
