I really liked your article, and the evolution of this syntax is historically interesting. But, your article did quite clearly claim that this use of 'else' is not English. You claimed 'else' is not a conjuction, and you called it a 'mystery' why it ended up in a computer programming language. I'm fine with, and actually I support the idea of being descriptivist about language rather that prescriptivist. But your comment here does unambiguously contradict what you wrote in the article...
