+    // files)

+    let id = mize.new_item();
+    mize.set(id.join("name"), "test-item");

+    //mize.on_update("5/name", |delta| println!(delta.new_value()));
+    //mize.update("5/name", "other-item")
+
+    // the goal is that also most things about the MizeInstance itself is controlled by
+    // get/set/update -ing values at the 0/ paths
