Very neat, and comes pretty close to how Mojo handles portable SIMD.
It's great to see two of my favorite languages finally making SIMD easy to use. It's such low-hanging fruit for performance, yet somehow languages have ignored it for years. Portable SIMD, even with some performance penalty, still beats scalar computation whenever vector operations are needed. Yet language implementations always seemed to assume that hardware-specific SIMD APIs were the only way to go. That did nothing but make SIMD unusable excepting special cases where performance is absolutely critical, rather than just something anyone can use in day to day programming.
