Unexpected productivity boost of Rust

Rust is one of a very few languages where I can make a total mess in my code by refactoring, have like 100+ compilation errors in multiple modules, think I’m never going to fix it, yet at the end of the day I eventually get everything to compile fine, I run the tests and… they all pass from the first go. All green. Hard to believe but it happened many times to me.

Same. I often have the experience of seeing my app suddenly work again and thinking "wait... I'm done?"
