Checking runtime object type

[H. S. Teoh]

What's the correct syntax for checking the runtime type of a derived
object given its base class pointer? I tried:

        Base f() { return new Derived(); }
        Base b = f();
        assert(is(typeof(b)==Derived));

but it throws an error. Apparently typeof(b)==Base; so typeof returns
only compile-time information? How do I get at the runtime type?
