This article was partially developed with the support of AI-assisted writing tools.
1. Background
- Contemporary mainstream languages such as C++ and Rust tend to “integrate everything,” resulting in overwhelming complexity. Developers are forced to confront the full feature set, creating substantial cognitive burden.
- Although C offers limited abstraction capabilities, its minimalist philosophy leads to clearer program structure and more controllable error surfaces.
- The current programming ecosystem is fragmented: assembly, C, Java, and JavaScript exist as isolated domains with inconsistent syntax and design philosophies. Developers must relearn mental models when transitioning across layers.
2. Core Principles
- Layering rather than stacking: Language features should be distributed across well-defined layers instead of being accumulated into a single monolithic language.
- Unified syntax: Hardware-level, system-level, application-level, and scripting-level languages should share a common syntactic foundation, enabling developers to work across layers with a single learning effort.
- Complexity allocated by necessity: The closer a language is to hardware, the fewer features it should expose; the closer it is to business logic, the richer the abstractions it should provide.
- Safety enforced at compile time: Ownership, borrowing, and lifetime mechanisms should operate purely during compilation, imposing no runtime overhead.
-
Escape hatches preserved:
unsafeblocks or inline assembly should remain available when needed to ensure flexibility.
3. The Layered Language Pyramid
- Hardware-Level Language
- Corresponds to assembly; direct manipulation of registers, memory, and interrupts.
- Fully manual memory and pointer management.
- Minimal macro-level abstraction.
- System-Level Language
- Corresponds to C or a “safe C” dialect.
- Introduces ownership, borrowing, and lifetime checks.
- Provides minimal concurrency and modularity support.
- Suitable for kernels, drivers, and database engines.
- Application-Level Language
- Similar in positioning to Java but significantly lighter.
- Incorporates limited object-oriented features (composition-first, interface-oriented).
- Offers standard libraries for containers, networking, graphics, and persistence.
- Suitable for enterprise applications and backend services.
- Scripting-Level Language
- Analogous to JavaScript.
- A dynamic subset sharing the same core syntax; supports interpretation or JIT execution.
- Gradual typing to facilitate rapid prototyping.
- Suitable for scripting, automation, and glue logic.
4. The V-ISA Concept (Virtual Instruction Set Architecture)
- Define a virtual instruction set at the BIOS/firmware layer, implemented in assembly as the foundational abstraction.
- Eliminate differences across CPUs and hardware platforms so compiler backends can target a unified V-ISA.
-
Benefits:
- More consistent boot and device initialization processes.
- More stable compiler backends and improved cross-platform portability.
- Unified debugging and safety guarantees.
-
Risks:
- Potential performance overhead; requires zero-cost mapping.
- Significant coordination challenges among hardware vendors.
5. Vision and Significance
- Developers are no longer forced to confront the full complexity of a single language; instead, they choose the appropriate layer based on their needs.
- Learning costs decrease as mental models become unified across layers.
- Ecosystems become continuous, with libraries and toolchains shared across the entire stack.
- Language evolution returns to a philosophy of simplicity, clarity, and maintainability rather than unchecked complexity accumulation.
6. Conclusion
This document is a conceptual draft rather than a complete language specification. Its purpose is to stimulate discussion:
- Should we reconsider the evolutionary trajectory of programming languages?
- Do we need a unified-syntax, clearly layered family of languages?
- Can breakthroughs be achieved at the hardware abstraction layer through a V-ISA?
