Thanks. Why use noexcept for everything except logical_not?


I noticed recently that the following worked, it will be convenient now we 
have those functors (for my own code, not the STL):

template<typename RandomAccessIterator, typename Compare = std::less<void>>
void sort(RandomAccessIterator first, RandomAccessIterator last,
          Compare comp = {});
