- 'if constexpr (...)' * instead of std::enable_if * terminate template recursion * compile-time elimination of code - use C++14 '_t', '_v' versions, eg, std::is_integral_v<T> instead of std::is_integral<T>::value - std::begin, std::end, std::void_t instead of prev stdFoam versions - provide is_contiguous_v<..> as short form of is_contiguous<..>::value with the additional benefit of removing any cv qualifiers. ENH: include is_rotational_vectorspace trait - tests for vector-space and nComponents > 1 (ie, not sphericalTensor) ENH: improve robustness of pTraits_.. tests by removing cv qualifiers
