Spamming them all over the place is a red flag imo
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.
Mojo has an even more portable simd[1] type that isn't just generic over length but also over type. In my opinion it is almost always better to specialize for each platform and use portable implementation as fallback. It's a shame that just very few languages support Zig-like comptime, because it would be excellent for specializations without introducing runtime penalties.
