Varargs with the same type is just a list. In many languages that could require an extra allocation, but in Rust that can just be a slice or maybe a an array with a const generic for it's size if you want to pass ownership. Varargs here would really just be a minor ergonomics improvement. Heterogeneous varargs would be more useful, but would require something like variadic generics. (which have been proposed before)
