Functional C++ for Fun and Profit
summary
Material demonstrates concrete techniques: use of lambdas and small functions to make C++ expression oriented, a builder pattern to keep domain objects immutable while allowing efficient construction, an immutable string + string-builder implementation that claims a real workload speedup (author estimates ~20–30%), and persistent associative structures (a persistent red‑black tree variant) that add roughly 10% overhead versus mutable sets while enabling cheap snapshotting and simpler concurrency.
