this decision was made for good reason, and i think that for Rust, we made the right call. I hope Rust++ or whatever doesn't follow this though

i can't recall a time where having to annotate a binding with mut actually saved me. it's just typing and one more compile/lint cycle i have to go through to get my code to compile

I'm fairly convinced i prefer _reading_ code with mut on variables. It gives me immediate hints whether I'm reading something that's done in an imperative vs. functional way
