Milestone: | To Be Determined | Component: | spirit |
Version: | Boost 1.56.0 | Severity: | Problem |

Description
It is not possible, for example, to use boost::iterator_range with spirit::basic_istream_iterator
clang++ -v clang version 3.6.0 (trunk 216817) Target: x86_64-apple-darwin14.0.0 Thread model: posix
using namespace boost; size (iterator_range<spirit::istream_iterator> ());
