Less abstract! Expressing Ruby OOP in pictures
summary
A visual language expresses Ruby OOP with little figures: arms = methods, fingers = arguments, objects as spawn platforms. It claims to make dependency injection obvious by showing dependencies flowing through fingers, models execution as a Rube‑Goldberg of method triggers, and exposes dynamic anti‑patterns (adding the same arg or condition across classes). An intern built a generator and a Rails app that comments PRs with these diagrams, and the notation is proven useful when refactoring the Sandy Metz example.
