Functional C++ For Fun And Profit
summary
Argues that C++ can adopt practical functional ideas: use C++11 lambdas and immediately-invoked lambda tricks to make expression-oriented code, prefer immutability with a companion immutable string with builder (move semantics + refcounts) for speed, and implement persistent data structures (shared nodes, atomic root swap) to simplify concurrency. Reports real-world use in financial code with benchmarks showing better string performance and roughly 10% overhead on persistent RB-tree ops, and much shallower ~3–5 hops using a hash-array mapped trie.
