If make_iterator_range() returned a const-qualified iterator_range<>, this would work. Thorsten?
Isn't the problem thet out is a reference?
out is a reference, which means that non-const rvalues will not bind to it. But const rvalues will because out_t will be deduced to be "iterator_range<> const". Try it and see. -- Eric Niebler Boost Consulting www.boost-consulting.com
