call to variadic function template without specified template arguments,
if constexpr,
c++11 attributes [[value]],
function templates with default parameters,
resolve order for function vs template with default parameter,
template operator->() with default arguments,
template specialization with numeric values,
find best partial specialization,
fix partial specialization for non-first specialized argument
