29.7.6 The gslice class [class.gslice] gslice access functions [gslice.access]

size_t start() const; valarray<size_t> size() const; valarray<size_t> stride() const;
Returns: The representation of the start, lengths, or strides specified for the gslice.
Complexity: start() is constant time.
size() and stride() are linear in the number of strides.
