He will like RUST very much.

Carmack had said he likes rust, he just isn't a language zealot. In rust though, the idiom would be to shadow intermediate variables often, which removes the debugger benefit.

There is no idiom about this. Do it if you like but clipply doesn't warn about any of it.

There isn't an enforced one, and the opinion is bifurcated, but I regularly find crates that clearly treat this as idiomatic practice.
