So if you're wondering how great #RustLang is, let's talk about #mypy. Mypy introduced its own Rust - #Python package, ast-serialize. This package had a deep crate dependency that was broken on PowerPC. The issue was fixed a month ago but everything is still blocked on a deep chain of dependencies being updated and released.

EDIT: yes, I know, it's not Rust, it's Cargo. Because obviously Rust without Cargo makes so much sense for that one project using it.
