There are often 2 consumers of your code: users and developers. If a developer can write error-free binary code that improves performance (as seen by the user) by 0.1%, BUT the next developer (or even the same dev months later) can't adjust the code without all hell breaking loose, then that code is basically awful. Side note: add your newline at the end of your files before commit! Ugh
