Hi,

I'm writing tests using the iterator_archetype 
[http://www.boost.org/doc/libs/1_55_0/libs/iterator/doc/iterator_archetypes.html] 
and get confused how to use a single_pass_iterator such as e.g.

iterator_archetype<int, readable_iterator_t, single_pass_iterator>

The default constructor does not work as expected (since 
single_pass_iterators are not necessarily default constructible). The 
copy constructor is not very useful and that is all can find. I noticed 
the  detail::ctor_arg and was hoping there were a constructor thaing 
that struct as argument - but no. How am I supposed to construct this 
class if I e.g. wanna passed it to a function that I intend to test.

Thank you,

Peter
