The code

enum class test { ZERO, ONE };

int main()
{
const test zero = test::ZERO;
int* x = zero;
}

can compile - it shouldn't

Details (expand)

Visual Studio 2012

1. Create an empty C++ console application
2. Enter the code
enum class test { ZERO, ONE };

int main()
{
    const test zero = test::ZERO;
    int*    x = zero;
}

3. Notice that it compiles without error

It the code is changed to
enum class test { ZERO, ONE };

int main()
{
    int*    x = test::ZERO;
}

it doesn't compile, but generates an
"error C2440: 'initializing': cannot convert from 'test' to int*"
which is correct
