#12472: accumulator statistics.hpp may cause build to fail due to no viable
overloaded operator[]

     Type:  Bugs                     |     Status:  new
Milestone:  To Be Determined         |  Component:  accumulator
  Version:  Boost 1.61.0             |   Severity:  Problem
 Keywords:                           |
-------------------------------------+--------------------------
 This occurred on both 1.61.0 and trunk. This was tested using Apple's
 Xcode 8 toolchain on macOS 10.12, through CMake, with Boost installed
 through Homebrew.

 This program shows the error on my computer:

 {{{
 #include <boost/accumulators/accumulators.hpp>
 #include <boost/accumulators/statistics.hpp>
 using namespace boost::accumulators;
 static accumulator_set<int, stats<tag::tail<right>>> acc;
 int main(int argv, char* argc[]) {
         return 0;
 }
 }}}

 Compilation was done using the command `clang++ -std=c++11 test.cpp`

 Interestingly, the build succeeds when `#include
 <boost/accumulators/statistics/tail.hpp>` is used instead of including
 `statistics.hpp`.
