About c3lang/c3c

C3 is a programming language that builds on the syntax and semantics of the C language, with the goal of evolving it while still retaining familiarity for C programmers. It is an evolution, not a revolution: a C-like language for programmers who like C. The c3c compiler offers full ABI compatibility with C, allowing seamless mixing of C and C3 in the same project. It features generics, type methods with dot syntax, and follows design principles such as staying close to C, data inertness, and avoiding unnecessary complexity. Precompiled binaries are available for Windows, Linux, macOS, and OpenBSD, and the compiler can also be built from source.
