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

[Alex Wang <aw1621107@…>]

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.

This appears to be present in the latest git checkout as of 30 Sept 2016, so the 1.62.0 release didn't fix this.

Never mind, this was my fault. This can be closed.
