Test code

Clang uses only 'template <class T> Stream& Stream::operator>>(T&)' and doesn't
see another matching definition 'template<class T> Stream& operator>>(Stream&,
std::vector<T>&)':

$ clang++ -std=c++11 -Wall -pedantic -Wextra test-sfinae.cpp 
test-sfinae.cpp:7:5: error: no member named 'Serialize' in 'std::vector<int,
std::allocator<int> >'
                t.Serialize(*this);
                ~ ^
test-sfinae.cpp:33:4: note: in instantiation of function template
specialization 'Stream::operator>><std::vector<int, std::allocator<int> > >'
requested here
        s >> data;
          ^
1 error generated.


Gcc 4.8.1 and 4.6.4 successfully compiles it. Clang without -std=c++11 as well.
