I've been wondering what the best way to implement SIMD in a JITless language was. While I'm a big proponent of static compilation (coding mostly in Go), this runtime inflexibility is a bit painful. Sure, you could compile multiple version, check the CPU and deliver the correct methods on runtime... but, that's not quite right. Another issue is how you code it up - both in terms of delivering multiple versions depending on CPU support and in terms of shielding the developer from low-level assembly. I'm all for high level APIs (think `sum(a vec, b vec)`) that get compiled down to whatever is supported, but I haven't seen many good examples of this.
