<i>Other languages</i>, not <i>all other languages</i> ^^. Yes of course there are several languages that map more directly to one&#x27;s mental model of how code is executed. Rust (which you&#x27;re working on) is an one such exception. Optimizations are certainly aggressive but the micro-optimizations are usually either well known (like NRVO, loop unrolling, function inlining), or not important relative to more costly operations that are occurring (allocations of heap memory, fetching from the heap, executing a system call, acquiring a mutex, etc).
