Why l (new runtime for k and q)
Summary
The article introduces l, a new runtime for K and Q, designed to preserve existing code while rebuilding the execution engine for modern hardware. It lays out four guiding ideas—SIMD by default, automatic parallelism, transparent fusion, and runtime-centric compression—aimed at delivering high performance without changing the language. It emphasizes full compatibility with existing K/Q code as a central guardrail.
