bad overloading

---
class A
{
public:
    void foo() const
    {}

    void foo()
    {}
};

template<typename R, typename T>
void test(R(T::*)() const)
{
}

int main()
{
    test(&A::foo); //Error here.
}

Details (expand)

Visual Studio 2010 SP1

class A
{
public:
    void foo() const
    {}

    void foo()
    {}
};

template<typename R, typename T>
void test(R(T::*)() const)
{
}

int main()
{
    test(&A::foo); //Error here.
}

it generates:
error C2914: 'foo' : cannot deduce template argument as function argument is ambiguous
error C2784: 'void foo(R (__thiscall T::* )(void) const)' : could not deduce template argument for 'overloaded function type' from 'overloaded function type'

the expected result is:
void A::foo() const should be matched by template function test()

error C2784: 'void foo(R (__thiscall T::* )(void) const)' : could not deduce template argument for 'overloaded function type' from 'overloaded function type'

void A::foo() const should be matched by template function test()
