80  * To make my own overloads of the intrinsics distinct I have to use a type that is inside the
81  * Vc::AVX namespace. To reduce porting effort and increase generality I want to use the same
82  * function names as used in the global namespace. The type name may not be the same, though
83  * because identifiers starting with two underscores are reserved by the standard. Thus using
84  * those would mean to depend on undefined behavior.
85  * Sadly a typedef is not enough.
86  * Public inheritance also does not work, because at least ICC considers the __m??? types to be
87  * some sort of fundamental types.
88  * Thus composition is the only solution.
