Hey,
wrapping my head around this atm..

so what you want is a static variable per subclass, but that the base
class can access.
What I would recommend is this:
abstract class Base
{
int x();
}
class A : Base
{
private static int _x = 1;
int x() { return _x; }
}
class B : Base
{
private static int _x = 2;
int x() { return _x; }
}
Note that this doesn't do *everything* a static variable can, since x()
requires an instance (i.e. you can't do A.x). But the actual variable
itself is static since the backing is static. This is the only way to
provide access of x to the Base that I can think of.
