`template< class T, class Abi = simd_abi::compatible<T> > class simd;`		(parallelism TS v2)

The class template simd is a data-parallel type. The width of a given simd instantiation is a constant expression, determined by the template parameters.

An ABI tag is a type in the simd_abi namespace that indicates a choice of size and binary representation for objects of data-parallel type.

Template parameters

T	-	element type; an arithmetic type other than `bool`
Abi	-	tag type used to determine the number of elements and storage

Helper alias templates

`template< class T, int N > using fixed_size_simd = std::experimental::simd<T, std::experimental::simd_abi::fixed_size<N>>;`
`template< class T > using native_simd = std::experimental::simd<T, std::experimental::simd_abi::native<T>>;`
