Argument Dependent Lookup Failure in Visual C++ 2010 by hanji

The following code snippet fails to compile under Visual C++ 2010:

template<typename T>
std::vector<T>
fun(const std::vector<T>& a, const std::vector<T>& b)
{
    std::vector<T> nrv;
    std::unordered_set<T> s(b.begin(), b.end());
    // msvc10 fails to find `remove_copy_if', where it should.
    remove_copy_if(a.begin(), a.end(), back_inserter(nrv), [&](T v) { return s.find(v) != s.end(); });
    return nrv;
}
