generate_ref and similar

The STL function generate (also for_each, etc) pass by value, which
may not be what you had in mind.  A simple workaround is something
like:

template<typename iter, typename gen>
void generate_ref (iter start, iter end, gen g) {
  generate<iter, gen&> (start, end, g);
}

Does boost contain any similar (or maybe more elegent) approaches to
this common problem?
