template <std :: size_t N> struct Since;

};Member type of valueList (see valueList). Creates subcollection of elements since N-th element till end (including N-th element). Giving N equal to size (see valueList :: size) represents empty collection. Giving N equal to 0 passes whole collection. If N is larger than size (see valueList :: size) compiler error Index out of range. will appear.
-
N- position of first element present in subcollection. Marks begining of subcollection.
-
type- source (see value source) for subcollection being created (for details see valueList :: Since :: type).
