Hi,
 I am trying to use phoenix::for_each to print each element of
iterator range.  Would appreciate if any clarification as to why
statements 1 and 2 are giving compile errors.

Thanks

//-------------code snippet

int x;
counting_iterator<int> first(0), last(10);
iterator_range<counting_iterator<int> > ir(first, last);
phoenix::for_each(ir, std::cout<<x<<' ')();
  //stmt 1 ; compile error
phoenix::for_each(ir, std::cout<<arg1<<' ')();
//stmt 2; compile error
