@coderanger @hynek 100%, and I am definitely not complaining when I use a project that's adopted uv and ruff and everything is almost implausibly fast. it's not really a *bottleneck* in my other projects, but I certainly don't mind the focus on performance that comes along with the choice of Rust.
I certainly don't object to Rust *qua* Rust, I depend on mountains of it in Cryptography and I wish I depended on more. but that's a different element of the stack with a very different context.
