Overview

This library provides the Set class, which deals with a collection of unordered values with no duplicates. It is a hybrid of Array’s intuitive inter-operation facilities and Hash’s fast lookup. If you need to keep values ordered, use the SortedSet class.

The method to_set is added to Enumerable for convenience.

See the Set class for an example of usage.
