I spent years dumbing down my code so J. Random Neophyte could read it, understand it, and make changes. I found out the hard way that JR is an untrustworthy witless dolt who should never be allowed to use a computer. He turns off the strict pragma because it does nothing except stop perfectly valid code from executing, and thinks that testing is a crutch used by incompetent programmers who don't know what to expect from their own code. I don't want JR to feel comfortable "fixing" my "executable line noise". I want JR to go back to flipping hamburgers where he belongs. And to receive at least two painful burns each week. On his face.
The greatest threat to continued habitability of the planet is people who are convinced of their knowledge of things they've never actually learned.
