You aren't.

If you have a non-const node, you can access its children non-constly _or_ constly (which you could do anyway, since you could make your reference to the node be const at any time). If you have a const node, you can only access its children constly.

This makes perfect sense.

My bad: didn't read the code carefully, thought that these were methods.
