Lumen
summary
A new BEAM compiler/runtime called Lumen targets WebAssembly, x86_64 and bare metal microcontrollers, drops hot code loading to enable ahead-of-time compilation and whole-program dead‑code elimination, and uses LLVM + MLIR and Rust for cross compilation and DOM access. An interpreter and compiler run demos: a spawn_chain stress test scales to thousands of processes (100 ≈100 ms, 1,000 <1 s) without blocking the browser UI, and the compiler produces a single standalone x86_64 executable that prints “Hello Lone Star Elixir 2020.”
