> if you […] often know better than the compiler

With all due respect, that tickles my spidey senses. People claiming to know better than a compiler about low-level details of their code are most often either engaging in premature hyper-optimisation, or suffer a specific kind of greybeard hubris IMHO

The idea that humans can't solve a specific problem more efficiently than a generalised algorithm that has to work for all code ever written in the language is a lie that JS script kiddies tell themselves to justify remaining ignorant without feeling bad about it.

		Oh, humans can definitely do that, in some capacity, if they're attentive, slept enough, aren't hungry, or in emotional distress, for a limited amount of time. A generalised algorithm can do this consistently, billions of times, which happens to be the amount of problems involved in building an application.
