>Description:
ns_tmp.cpp: In function `void F<int>(int)':
ns_tmp.cpp:15:   instantiated from here
ns_tmp.cpp:10: `AF' undeclared (first use this function)
ns_tmp.cpp:10: (Each undeclared identifier is reported only once
ns_tmp.cpp:10: for each function it appears in.)
>How-To-Repeat:
namespace A
{
	template<class T> void AF(T x) { }
};

template<class T> void F(T x)
{
	using namespace A;

	AF(x);
}

int main(void)
{
	F(3);
	return 0;
}
>Fix:
namespace A
{
	template<class T> void AF(T x) { }
};

template<class T> void F(T x)
{
	using namespace A;

	A::AF(x);
}

int main(void)
{
	F(3);
	return 0;
}
