Shouldn't this work?
//...
class Cls
{
int k;
static int foo() { return 0; }
}
//...
The deal is that int foo() by itself is an instance method, but static
declares it a class method, which is what you want -- class methods are
shared, so you can simply call (or dereference) them without instances.
