This should compile and run without error/exception.

using System;

struct S
{
    public static void Main ()
    {
        S? s = null;
        A a = s;
        B b = (B) s;
    }
}

class A
{
    public static implicit operator A (S x)
    {
        return new B ();
    }
}

class B : A
{
}


- Will probably have to create LiftedUserOperator to emit EmitCheck.
- How does it work with ET?
