yeh, but likewise I don't see `fn double(arg: u32) -> arg * 2` an issue if you want to contract the syntax. using multiple lines requires {} it's got nothing to do with the "type" of function. Unless function and lambda are different beasts, I'm still learning. `|arg| arg*2` and also `|arg| { arg * 2 }` I'm not really a fan.
