In order to design a modern and competitive C-style programming language, it is essential to critically analyze the dominant and emerging players within this family. C-style languages are united by a common structural syntax—block delimiters using braces {}, statement terminations using semicolons ;, infix expressions, and relatively low-level control over memory and computation. However, the design philosophies, target domains, and evolutionary trajectories of these languages diverge significantly.
This section presents a focused analysis of C, Go, Rust, and Zig—each of which has carved out a strong position in systems programming, and each with implications that must inform any new language effort. The evaluation reflects key design principles, recent language developments (2019–2024), and what modern C++20/23 can leverage from or improve upon.
Overview: C remains the foundational language of system software and low-level development. It is prized for its predictable performance, direct memory manipulation, and minimal runtime overhead. However, it suffers from lack of safety guarantees, absence of modern abstractions, and an outdated toolchain philosophy.
Strengths:
Extremely small and portable runtime
Full control over memory layout and hardware interaction
ABI stability and mature compiler infrastructure (GCC, Clang)
Limitations:
No concept of modules, generics, or strong typing beyond structs and unions
High risk of undefined behavior and buffer overflows
Poor support for concurrency abstraction and memory safety
Implications:
Any new C-style language must honor C’s performance ethos while enforcing stricter compile-time guarantees. Using C++20/23 features like concepts, consteval, constexpr allocation, and strong typing via variant and optional, one can address safety and abstraction without sacrificing control. C remains a baseline reference, not a model to replicate uncritically.
Overview: Go (or Golang), developed at Google, emphasizes simplicity, concurrency, and developer productivity over feature-rich abstraction or low-level control. It targets backend systems, microservices, and cloud infrastructure.
Strengths:
Minimalist syntax; easy learning curve
Built-in garbage collection and CSP-style goroutines for concurrency
Static binaries and cross-compilation ease
Limitations:
No generics until 2022; limited metaprogramming support
Garbage collection introduces unpredictable latency
Weak abstraction capabilities for low-level system tasks
Recent Developments:
Introduction of type parameters (generics) in Go 1.18
Continued refinement of the module and toolchain ecosystem
Implications: Go demonstrates that developer ergonomics and consistent tooling matter, especially for adoption. However, its lack of deterministic memory handling, compile-time evaluation, and low-level control makes it unsuitable as a foundation for embedded or real-time systems.
A modern C++ interpreter can adopt Go’s clean module system and error-handling discipline (e.g., explicit error return values), but should reject its garbage-collected runtime in favor of RAII and move semantics offered by modern C++.
Overview: Rust is the most radical rethinking of C-style programming in the last decade. Its central feature is ownership-based memory safety, enabling deterministic memory management without garbage collection. Rust’s goal is to eliminate entire classes of bugs at compile-time.
Strengths:
Ownership and borrowing model enforce memory safety
Zero-cost abstractions via monomorphization and inlining
Strong concurrency model: Send, Sync, and thread safety by design
Macro system and rich type inference
Limitations:
Complex syntax and steep learning curve
Slow compile times due to heavy monomorphization
Lack of reflection or runtime code generation
No stable ABI; challenging to integrate with other languages dynamically
Recent Developments:
Stabilization of const generics and async improvements
Ecosystem growth in embedded, web (via WebAssembly), and OS development
Initiatives like Rust-for-Linux and cargo standardization
Implications: Rust proves that compile-time memory safety is viable without garbage collection. However, its complexity, especially around lifetimes and trait resolution, often deters new users.
A C++20/23-based language can adopt similar safety models using unique_ptr, span, std::optional, and concepts, while offering easier integration with C++ or C. Moreover, with constexpr and consteval, C++ can now mimic many of Rust’s compile-time guarantees in a more familiar syntax.
Overview: Zig is a newer C-style language focused on manual memory management, simplicity, and performance transparency. It aims to replace C in domains like OS kernels, embedded systems, and performance-critical applications.
Strengths:
No hidden control flow: no exceptions, macros, or GC
Compile-time code execution with comptime
Manual memory allocation with explicit ownership patterns
Strong interop with C (drop-in C replacement)
Limitations:
Limited ecosystem and tooling maturity
Verbose allocation patterns compared to higher-level languages
Fewer abstraction tools than Rust or C++
Recent Developments:
Enhancements to the Zig build system and cross-compilation
Growing use in game engines, graphics, and system bootloaders
comptime as a language-native alternative to templates or macros
Implications:
Zig embraces full transparency and user control, rejecting language complexity and automation. It shows that a well-designed compile-time execution model (akin to consteval in C++20) can replace preprocessor macros and support meta-programming safely.
A new C-style language built in C++ can achieve similar goals using:
constexpr classes and expressions
std::array, std::bit_cast, and fixed-layout structs
concepts and tagged unions (std::variant) for compile-time safety
Zig’s design reinforces the idea that simplicity and predictability are as valuable as expressiveness in systems programming.
| Feature / Language | C | Go | Rust | Zig |
|---|---|---|---|---|
| Memory Safety | No | Partial (GC) | Yes (Ownership) | Manual, Explicit |
| Concurrency Model | Low-level | Goroutines | Compile-time Safe Threads | Manual |
| Compile-time Eval | Preprocessor | Limited | const fn, macros | comptime |
| Metaprogramming | None | Weak | Macros, Traits | comptime |
| Interop with C | Native | Good | Good but indirect | Excellent |
| Toolchain Simplicity | High | Very High | Moderate | Moderate |
| ABI Stability | Yes | Yes | No | Yes |
| Runtime Overhead | None | GC overhead | None | None |
Each of the analyzed C-style languages provides distinct lessons for the design of a new programming language:
From C, we learn the importance of transparency and control, but also the risks of underspecified behavior.
From Go, we take inspiration in simplicity and developer experience, while avoiding its runtime abstraction costs.
From Rust, we inherit safety, concurrency, and expressive power, while seeking a gentler learning curve and interoperability.
From Zig, we embrace manual control, predictability, and modern compile-time evaluation, refined with better abstraction support via modern C++.
The modern C++20/23 standard is now powerful enough to serve as the implementation platform of a new interpreter or language runtime that integrates these lessons. With concepts, modules, consteval, jthread, std::span, and rich type algebra, C++ empowers developers to encode safety, performance, and modularity directly into their language infrastructure—delivering both pragmatism and precision in language design.
