hrmm can i make a binary tree with D?
seems it doesnt like having a pointer to a class inside a class?

eg:

Node
{
Node pointer;
}

is this possible yet with D?

Have you written a complete program that shows how it doesn't like this yet?  Have you tried compiling it yet?  Have you come up with an exact error message yet?

Yes, as far as I know.

I've used this... for example, some code from a database converter I semi-recently wrote:

------------------------------
// . . . some junk
class DBObj {
    // . . . some junk

    DBObj    parent,
             children,
             children_next,
             location,
             contents,
             contents_next;

    // . . . some junk
}
------------------------------

So I must not understand what the problem is...

What you are trying is _NOT_ possible.

"Node" should be "class Node" or "struct Node"
Then it should work
Have a look at my dlinked list at http://d.wienczny.de

Huh?  I do see a minor syntax error...but the code is basically valid. You can do this:

class Node {
	Node pointer; // this is a reference to a class object
};

or this:

struct Node {
	Node *pointer;
};
