:mrdocs:

This `struct` template implements the `is_class` meta‐function defined in the C++11 standard [meta.unary.cat]to determine if the (template parameter) `t_TYPE` is a class. Note that for implementations without native library support, this component will mis‐diagnose `union` types as classes. This would be correct according to the core language definition of a class type, but is an error according to the standard library definition of this type trait.
