New description:
A general tool to define:
* PositiveInteger
* NonNegativeInteger
* More.....
The idea is :
Range(begin, end, step) returns a proper finite/infinite set with
categories of the defined set as you think...
(12:37:41) hivert: For example but not only: Range(5, 2**1321312, 3)...
(12:38:09) hivert: Range(0, Infinity, 1) <=> NonNegativeIntegers
(12:38:18) hivert: Range(1, Infinity, 1) <=> PositiveIntegers
