Turning with and except into readable expressions without needing to add new custom syntax for each was my initial motivation. It's possible there are only a handful of such cases, and only one of them is important enough to be worth doing, in which case custom syntax for that one is the best answer. But given that half the proposals on this list are for some form of new expression syntax, I'm not sure that's the case.
