#9750: iterator_range<T> to iterator_range<T const> & implicit conversion
------------------------------+--------------------------
 Reporter:  psiha             |      Owner:  neilgroves
     Type:  Feature Requests  |     Status:  new
Milestone:  To Be Determined  |  Component:  range
  Version:  Boost 1.55.0      |   Severity:  Optimization
 Keywords:                    |
------------------------------+--------------------------
 Please add:

 operator iterator_range<T const> /*const*/ & ( ) /*const*/ { return
 reinterpret_cast<iterator_range<T const> /*const*/ &>( *this ); }

 ...as this is more efficient with functions that take iterator_ranges by-
 ref on compilers w/o the SRA optimization (or on ABI boundaries) and,
 AFAICT, should be safe WRT strict-aliasing-rules...
