The Functional Rubyist
summary
Claims Ruby supports practical functional programming and demonstrates it with working code: shows currying and partial application via add.curry, builds generic find_multiples and individuated variants, implements streams using 1.. (infinite range) and lazy to get first N multiples, and enables tail-call optimization (require plus accumulator) to compute huge factorials — demo runs factorial(24000) without stack overflow. Talks through the exact Ruby methods and patterns used and the concrete results they produce.
