28.6 Numeric arrays [numarray]

28.6.4 Class slice [class.slice] Constructors [cons.slice]

slice(); slice(size_t start, size_t length, size_t stride);
The default constructor is equivalent to slice(0, 0, 0).
A default constructor is provided only to permit the declaration of arrays of slices.
The constructor with arguments for a slice takes a start, length, and stride parameter.
[Example 1: 
slice(3, 8, 2) constructs a slice which selects elements from an array.
