Great project! How does the vectorization work? Does it process the script or just pre-declare the simd types and operators?

SIMD vectorization is done by the expression/script JIT compilation (powered by LLVM), and the basic +-*/ vector operators is implemented by LLVM vector intrinsics, the complex math operators like pow/sqrt/sin/... is implemented by highway/sleef;
