I would have said that you should not override the variable, just the
initialising code in a static constructor.

abstract public class X
{
protected static string var;

protected static SetVar(string value)
{
var = value;
}

static X()
{
SetVar("X");
}

public static void print_my_var()
{
Console.WriteLine("my var is " + var);
}
}

public class A : X
{
static A()
{
SetVar("A");
}

But this doesn't work either as it appears that the only static constructor
to be called in class A is X().

I must admit that this is not as I would have expected. Does anyone know if
this is a bug in beta 1 ?
