List
list of variables or domain values

Description

Constrains all list elements to be different values of the same domain. This is implemented by mapping onto ic_global:alldifferent/1. All list elements must be variables or values of the same domain. If one or more of them are domain-less, they will be given the same domain as the others.

Modules

This predicate is sensitive to its module context (tool predicate, see @/1).
