Detailed Description
template<typename _RAIter, typename _Compare>class __gnu_parallel::_GuardedIterator< _RAIter, _Compare >
_Iterator wrapper supporting an implicit supremum at the end of the sequence, dominating all comparisons.
The implicit supremum comes with a performance cost.
Deriving from _RAIter is not possible since _RAIter need not be a class.
