I get really twitchy when I read statements like yours. But I am completely unreasonable in my definition of perfect -- it is really beyond extreme. Perfect is an absolute, so by definition it is unobtainable. Perfect means you have gone beyond the notion of executes correctly every single time, but MUST also be aesthetically perfect. Perfect names, perfect formatting, perfect location etc. No one can meet my criteria for perfect and never will (I can't).
In that sense, there is no perfect code, nor will there ever be. There will only EVER be good enough.
You’ve created a concept and attached the word “perfect" to it. Your concept is different than the shared definition. This leads to disagreements, misunderstandings, and (as you said) twitching.
The purpose of words is to share information. If you have write a paragraph describing your definition when you use a word, use a different one.
Perfection is subjective because flaws are subjective. Aesthetics are part of the code. If a piece of code is functionally perfect but ugly or inelegant by some measure, then it is imperfect by that measure.
In that sense, there is no perfect code, nor will there ever be. There will only EVER be good enough.
