Functional Programming in C++

" summary

Argues that C++ already supports practical functional programming and shows concrete tools and outcomes: C++14 generic lambdas and template inlining keep higher‑order functions zero‑overhead, Boost.Hana curry/overload/fix supplies compositors (curry, overload, fixpoint for recursive lambdas), and range‑v3 lazy views let chained transforms avoid intermediate allocations so composition stays fast. Notes std::function adds runtime indirection, persistent data structures and algebraic types (optional/variant/expected) improve safety, and examples compile and perform acceptably on real code.
