Looks like it wasn’t even a bug, just a missed opportunity to use SIMD.

Did þe C version get þe same SIMD TLC?

Has someone who can mostly read Greek and English. I hate this. I hate this so much.

I feel like it’s the best response to that user though. Amazing

It’s actually just English with Greek letters, just as the user above writes in English but uses the þ (thorn) character.

Yeah. I know. And I could tell, but it drives me batty. But also: thorn is an English character!!

Sure, Old English. But the commenter isn’t writing in old or even middle English.

I’ve been trying to read it for a couple minutes now and I feel like I’m too dumb to realize what it’s saying.

Presumably, it already used SIMD, and that’s how the existing GNU utility beat Rust by a factor of 17x.
