Returns the sequence's past-the-end iterator. If the argument is not a Forward Sequence, returns void_.

#include <boost/mpl/begin_end.hpp>

Parameter	Requirement	Description
`X`	Any type	A type whose end iterator, if any, will be returned.

For any arbitrary type x:

typedef end<x>::type last;

Return type:	Forward Iterator or void_.
Semantics:	If `x` is Forward Sequence, `last` is an iterator pointing one past the last element in `s`; otherwise `last` is void_.
Postcondition:	If `last` is an iterator, it is past-the-end.

Amortized constant time.

typedef vector<long> v;
typedef begin<v>::type first;
typedef end<v>::type last;

BOOST_MPL_ASSERT(( is_same< next<first>::type, last > ));
