Defined in header <experimental/simd>
template< class T, class Abi = simd_abi::compatible<T> >
class simd_mask;
(parallelism TS v2)

The class template simd_mask is a data-parallel type with the element type bool. The width of a given simd_mask instantiation is a constant expression, determined by the template parameters. Specifically, simd_mask<T, Abi>::size() is always simd<T, Abi>::size().
