FunctionalPlus is a small, header-only C++ library providing pure functional programming helpers like keep_if, forward application, and function composition. It aims to make C++ code more concise and readable by replacing boilerplate loops and iterator plumbing with high-level, self-documenting functions.

Use cases

• write concise and readable C++ code
• filter, transform, and reduce STL containers without hand-written loops
• compose and forward-apply functions in C++
• reduce iterator boilerplate when processing collections
• write pure functions over ranges in C++14/17

When to choose

• you want functional-style collection manipulation in plain C++ without heavy dependencies
• you need a header-only library that works with C++14 or C++17
• you prefer readable one-liners over manual for loops and std::copy_if calls

When to avoid

• you need full lazy range pipelines with views and actions, where range-v3 or C++20 ranges fit better
• your project targets C++11 or older standards
• you need runtime performance tuning beyond what STL algorithms already provide
