--- Comment #5 from RazvanN <razvan.nitu1305 at gmail.com> ---
Right now, if we modify the element of a foreach range, there is no problem
because we are operating on a copy of the original element. If we need to
modify the actual element, then we need to add ref. That stands true for the
iteration variable also. I don't see why we would deprecate any of this
behavior because it offers maximum flexibility.
