Thread: Ambiguous operator?

Ah yes, from one problem to the other. Template friends are just a pain; this solves the ambiguous operator, but fails to make the friend declaration work. Wonderful, that's what I call it.
Good thing I decided to use an easier approach.

I'm not even going to bother with this approach anymore >_<

EDIT:
Actually, this works!

Code:

#include <iterator>
#include <iostream>

template<typename T, bool ReadOnly> class buffered_stream_iterator;

template<typename T, bool ReadOnly, typename T2> T2& operator += (T2& lhs, const buffered_stream_iterator<T, ReadOnly>& rhs);

template<typename T, bool ReadOnly>
class buffered_stream_iterator:
	public std::iterator<std::random_access_iterator_tag, T>
{
public:
	template<typename, bool, typename T2> friend T2& operator += (T2& lhs, const buffered_stream_iterator<T, ReadOnly>& rhs);

private:
	int m_Test;
};

template<typename T, bool ReadOnly, typename T2> T2& operator += (T2& lhs, const buffered_stream_iterator<T, ReadOnly>& rhs)
{
	std::cout << rhs.m_Test;
	return lhs;
}

int main()
{
	buffered_stream_iterator<wchar_t, false> Test;
	int n = 0;
	n += Test;
	return 0;
}
