#11528: MSVS 2015 + boost::range: STL and Boost iterators
--------------------------------------+------------------------
 Reporter:  Dennis Schneider <dsr@…>  |      Owner:  neilgroves
     Type:  Bugs                      |     Status:  new
Milestone:  To Be Determined          |  Component:  range
  Version:  Boost Development Trunk   |   Severity:  Problem
 Keywords:                            |
--------------------------------------+------------------------
 The attached test program compiled with MSVS 2013, but doesn't with
 MSVS2015 in debug mode and Boost-trunk as of 2015-08-05.  The
 `transform_iterator` is recognised as Boost foward iterator, but only as
 STL input iterator because its reference type is `int`.
 Since `boost::max_element` uses `std::max_element`, it doesn't compile in
 debug mode with:
 {{{
 c:\program files (x86)\microsoft visual studio
 14.0\vc\include\xutility(1005): error C2338: next requires forward
 iterator
 }}}

 I'd be happy if this code compiled and worked, or if otherwise the Boost
 assertion would fire because the transform iterator is not a Boost forward
 traversal iterator.
