Real-world Functional Ruby
summary
A concrete claim: Ice Lab ships more than 10 apps in two years using this style with teams of two or three, proving it scales beyond toy examples. Code models behavior as immutable verb-named functional objects with constructor dependency injection wired by dry-system + dry-auto_inject, results as monads via dry-monads, typed value objects with dry-types/struct and validations via dry-validation, views with dry-view, HTTP via dry-web-roda and persistence via ROM. Tests mock injected deps and focus on small units.
