I haven't read OP yet but I don't see what is the issue here. I honestly think what you see as issues are perhaps because of your lack of exposure to a wider range of languages? CF clearly is a prefix for a library. I'll take an educated guess it means Core Foundation? Pretty common pattern of naming things, with +/- to be certain. And once you've seen it, it is just there, and you know precisely what it means. So 10 minutes of your life to learn what CFxxx() means. Let. I like lets. Some don't. Surely we can coexist? x..y is also not unique to Swift. It has a nice mathematical look to it, is more concise. Btw, is that 'range' in Python inclusive or exclusive? It isn't clear from the notation. Must I read the language spec to figure that out? .. /g
