Your trivial proof is "this thing that is explicitly not part of the language"? The whole point of comments is to say "these next characters are not part of language -foo-, so don't compile/interpret them".
And if you notice, comments are written in a 'traditional' human language, usually English.
if code wasn't a human language we'd write it in binary, straight to disk.
I can see my belt, but that doesn't mean the purpose of my belt is to be seen. You're twisting my original comment to say something it didn't say.
