I'm trying to look at things not just in terms of "what would be useful", although that's important. I'm looking at the overall design of the language, and understand the way all the parts fit together into a beautiful whole. It's an aesthetic thing, which I can appreciate may be a little difficult to swallow. FWIW, I would restate the argument as follows: 1) Arrow functions "express" mappings 2) Generators "express" sequences 3) Don't muddy the waters Anyway, I'm not really trying to convince anyone. I just think we should reserve the right to have this discussion later, and not prematurely commit to "=!>" or whatever.
