Hi,

valac said "missing generic type arguments", so I simply added them:

public class Main : Object
{
public static HashMap<int, Node?> map;

static int main ()
{
map = new HashMap<int, Node?>((Gee.HashDataFunc)GLib.direct_hash,
 (Gee.EqualDataFunc)GLib.direct_equal);
var b = data();
var node = new Node();
node.c = {'a', 'b'};
node.d = &b;
map[1] = node;

return 0;
}
}

After that I still had to cast the GLib hash and compare functions to
their Gee counterparts, but now it just compiles. I'm not sure if that
means it does what you want it to though..
