Improve Stats definition Use operator const T&() instead of operator T() to avoid possible costly hidden copies of non-scalar nested types. Currently StatsEntry has a single member T, so assuming sizeof(StatsEntry) == sizeof(T) it happens to work, but it's better to use the size of the proper entry type in std::fill. Note that current code works because std::array items are ensured to be allocated in contiguous memory and there is no padding among nested arrays. The latter condition does not seem to be strictly enforced by the standard, so be careful here. Finally use address-of operator instead of get() to fully hide the wrapper class StatsEntry at calling sites. For completness add the arrow operator too and simplify the C++ code a bit more. Same binary code as previous master under the Clang compiler. No functional change.
