I see no benefit instead of using a normal if construct. This guard syntax has more keystrokes, doesn't read like "normal" English, has massive BC implications. I don't see why this would encourage defensive programming as you still need to write code with this in mind. Moreover, we already have assertions [1] although they could be improved, I'd rather have this be the focus than introducing this guard proposal. Best regards George P.
