FunctionalPlus

Integration is trivial without build system hassles; just include fplus.hpp as shown in all examples, making it easy to drop into any project.

Functions like fplus::keep_if offer side-effect-free transformations that make code self-documenting, reducing boilerplate compared to hand-written loops as demonstrated in the introduction.

Uses function_traits to automatically deduce types and provide clear compile-time error messages, helping catch bugs early without cryptic template errors.

With fplus::fwd::apply, you can chain functions in a readable pipeline style, similar to command-line tools, enhancing code flow as shown in the gemstone tutorial.

Works out-of-the-box with standard containers like std::vector and std::string, and supports custom types with similar interfaces, ensuring broad compatibility.
