Functional C++

" summary

Argues that applying functional techniques to modern C++ yields clearer, safer, testable code without losing runtime performance: uses std::function and lambdas, const qualifiers, rvalue references and move semantics for zero-copy value semantics, and selective caching to fix perf hotspots. Demonstrates channels built from mutex/condition_variable, futures/async, a pipes-and-filters FizzBuzz and Friday-13 generator, and an actor-style phonebook; warns that naive shared_ptr chains cause recursive destructors (stack overflow for thousands of nodes) and recommends persistent data structures and channels and actors for scalable concurrency.
