My only real question is why we need to forbid short-closures. I fully agree that capturing variables for such functions doesn't work. What I don't understand is why that precludes short-closures. Is it not possible to "just" say "there's nothing to even capture in this context, don't try"? (There may be technical reasons for that, but I do not know what they are and the RFC doesn't say.) --Larry Garfield
