I don't see why this wouldn't work, if you've in fact covered all combinations.
It works, the problem was that castSwitch returns something and I
didn't "catch" it.
It's similar to how castSwitch is implemented, though the double casts
are in

sounds like foo should just be a method in the class rather than a free
function
In my particular case I want to keep some stuff outside of claases.

From the docs:
class A { }
class B : A { }
class C : B { }
void foo(A);
void foo(B);
void test()
{
C c;
foo(c); // calls foo(B)
}
I need the other way around. So, at runtime I get an A and depending on
it's dynamic type, I would like to get the correct foo() called.
class A { }
class
