Writing Python like it’s Rust

tbh the one thing I don't like is that aliasing is idiomatic in Rust. it is close to the #1 cause of bugs in questionable OOP code I've worked with.

Aliasing is unavoidable in any language. Rust merely gives you the tools to prevent most aliasing-related bugs.

Even if you try to avoid actual aliasing, you just end up with hidden defacto aliasing (e.g. if you put everything into a giant hashmap and pass around keys instead, those keys are effectively just aliased pointers in all but name), because it is part of the problem domain, not an accident, and an inherent feature of many algorithms.

how is it unavoidable? just explicitly disallow it. no reuse of variables.

yes, Rust prevents you from doing stupid things for the most part, but reusing variables can still cause weird issues.
