subscript(_:)
Extracts the scalars at specified indices to form a SIMD64.
subscript<Index>(index: SIMD64<Index>) -> SIMD64<Self.Scalar> where Index : FixedWidthInteger, Index : SIMDScalar, Self.Scalar : SIMDScalar { get } The elements of the index vector are wrapped modulo the count of elements in this vector. Because of this, the index is always in-range and no trap can occur.
