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.
