You are also assuming one prompt, and then arguing against your assumptions with zero evidence. It is lazy arm chair criticism.
Because it hasn't been released yet (at least not outside of some unstable branches). You can find some criticism of the actual slop here though: https://old.reddit.com/r/rust/comments/1t4033y/buns_rewrite_...
I’m curious if that matters if humans are never going to even read this code?
If by never even read you don't include attaching a debugger to solve an issue. 1,000 global mutable variables would make debugging anything an absolute nightmare.
