At some point, the compiler is smarter than you are.

Whether it can do your use case better than you can comes down to "how many other people had this problem before"?^[aq]

The more likely other people have had it, the more likely it's been optimized.

Not how often you've had this use case before, but the absolute number of how many people over time.

If it's an area you aren't a world expert in, then it's likely the compiler is smarter than you.
