Proxy: Next Generation Polymorphism in C++

C++17 library for comfortable and efficient dynamic polymorphism

C++17 Run-time Polymorphism (Type Erasure) library

Fast containers of polymorphic objects.

:fish_cake: A new take on polymorphism

Open-hierarchy Fast RTTI framework for C++17 and up with support for multiple inheritance and dynamic casting.

Zero boilerplate generic type erasure, powered by C++26 reflection.

variant lite - A C++17-like variant, a type-safe union for C++98, C++11 and later in a single-file header-only library.

Extensions to the C++ standard library. This library implements polyfills to enable library functionality from later versions of C++ to be used in earlier versions. It also implements some nonstandard but useful extras.
