A switch/case too far...

I like the following idea: if the case statement specifies a type,
check that the object can be implicitly cast to that type; if the case
statement specifies a value, check for equality. So:

    switch(typeof(a))
    {
        case B1: // RTTI dynamic cast test
            // ...

        case B2:
            // ...
    }

But

    switch(a)
    {
        case a1: // equality test
            // ...

        case a2:
            // ...
    }
