Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Provides a FIFO set with a maximum size. Adding an element after the capacity has been reached kicks the oldest element in the set out, while maintaining the uniqueness property of a set (relying on #eql? and #hash).
