inside a bunch of nested loops is where you need a goto, if the language doesn’t have labeled breaks (which is just a fancy goto)

most of your points are things people notice any time real actual big software with performance constraints gets posted. so along with questioning the wisdoms in that function, also question your own wisdom. maybe some of what you think you know is wrong.

Code like this actually always makes me feel better about my own code when I’ve ultimately had to make a trade off between abstraction/organization and performance. I wonder who all these engineers are that see code like this, especially in hot paths, and can’t understand how it came to be and that there was a deliberate choice made.
