Extreme Object-Oriented Ruby
summary
Claims that Ruby can be restricted to a pure OO numbers model and that keywords like if are unnecessary; implements numbers as Zero and Successor objects, defines + and == by delegating to predecessors, and models true/false as objects so conditional logic becomes an object-if pattern. Uses only defining classes instantiating objects storing references and sending messages and maps lambda calculus into those objects. Rebuilds arithmetic and boolean logic successfully but discovers no IO and eager evaluation issues that prevent full parity.
