Boost :

I ran into the following problem. I have an algorithm which looks like:

template<typename in_t, typename out_t>
void Alg (in_t in, in_t inend, out_t out) {
  for (; in != inend; in++, out++)
    do_something()
}

Now if I want to call this algorithm more than once, it would be convenient
to pass out by ref, so it would be incremented:

Alg (v.begin(), v.end(), boost::ref (out))
that is, pass a reference to some kind of output iterator

this fails, because boost::ref doesn't have operator++ defined for
reference_wrapper.

My question is, should boost::ref forward operators like ++ so that this
would work?
