12472,accumulator statistics.hpp may cause build to fail due to no viable overloaded operator[],Alex Wang <aw1621107@…>,Eric Niebler,"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`.
