This is excellent and I wholeheartedly commend you for writing about this subject. I personally have a knack at pre-mature optimization. I’ve announced that aloud at work on several occasions. I generally don’t have a good excuse for it other than it being more terse, reusable, functional, easier to read or simply optimized for performance. My argument unfortunately becomes weak to other programmers that come from AOT piled language worlds. It really does come down to how the compiler will interpret your code. I would consider such optimizations to improve compile time at micro levels. Does this still hold the argument strong about pre-mature optimization?
