It's so funny to see a "compiler is magic" people encountering reality in the wild. No, an algorithm that must work for every single user of the language cannot possibly optimize for every individual's use case. It is trivial for hand-written code to outperform a compiler on bespoke use cases. That anyone perpetuated otherwise was a lie they told themselves to feel secure in their ignorance and incompetence, because it's more comfortable to excuse your lack of skill if you believe that no human could ever out-perform a compiler. The saddest part is the barrier isn't even that high. You, and the rest of the magical compiler religious believers, could learn to do this, if only you tried instead of believing in your fairy tale.
