class ObjectRange

Description

A succession of values.

An ObjectRange can model a range of any value that implements a succ method (which links that value to its "successor").

Prototype provides such a method for Number and String, but you are (of course) welcome to implement useful semantics in your own objects, in order to enable ranges based on them.

ObjectRange mixes in Enumerable, which makes ranges very versatile. It takes care, however, to override the default code for include, to achieve better efficiency.

While ObjectRange does provide a constructor, the preferred way to obtain a range is to use the $R utility function, which is strictly equivalent (only way more concise to use).

See $R for more information.
