What about someone reading the code? He/she would either have to go through the remainder of the function/scope to make sure that `arg` was not being used (if it were, then it was a borrow, otherwise, it could have been either a borrow or a move); or they would have to look at the signature of `foo()`; as opposed to just being able to tell right there at the call site. -- Ziad
