That sounds like the similar, but opposite case of tail recursion optimization. Some languages/compilers don't do it because devs want stack traces. But allow TCO in and now the code that gets written is quite different than the code that would not do tail calls because TCO doesn't exist. Also a surprising amount of undefined behavior gets relied on in code. I don't use Rust, but the idea that they could potentially change the future behavior on overflow seems... risky? |
