The C3 programming language has emerged as a modern alternative to C, focusing on enhancing features while maintaining compatibility with existing C ABI. Users have expressed positive experiences, especially for tasks like CSV parsing and creating simple CLI tools. Although it has typical pre-1.0 bugs, users appreciate its improvements over C. A notable potential enhancement in the future is the addition of tagged union types. The community is also curious about compatibility with optimized compilers like clang and gcc, similar to other languages such as VLang and Nim. Overall, the development of C3 marks a significant milestone in programming languages, potentially filling a niche for developers seeking a more robust tool without departing from familiar C paradigms.
