   I'll add benchmarks soon; I'm trying to make it usable first ;). Right now, it's within 5% of ugly-style explicit SIMD code in the absolute worst case (the example in the README is more like 1%). The hot bit (the body of the

   LLVM and rustc are pretty fickle with what they'll autovectorize. The idea of faster is to make things which are impossible to autovectorize easy to write as SIMD. A few examples I'm targeting for the next point release are matrix

   Sadly, even something like [1.0f32].map(|s| s.sqrt().abs().recip()).collect() doesn't get vectorized 99% of the time; you can check the disassembly and you'll see sqrtss et al.
