+/// Accepts a closure-like syntax to call arbitrary code on a menu item
+/// after matching against `kind` and retrieving it from `resources_table` using `rid`.
+///
+/// You can optionally pass a third parameter to select which item kinds
+/// to match against, by providing a `|` separated list of item kinds
+/// ```ignore
+/// do_menu_item!(|i| i.set_text(text), Check | Submenu);
+/// ```
+/// You could also provide a negated list
+/// ```ignore
+/// do_menu_item!(|i| i.set_text(text), !Check);
+/// do_menu_item!(|i| i.set_text(text), !Check | !Submenu);
+/// ```
+/// but you can't have mixed negations and positive kinds.
+/// ```ignore
+/// do_menu_item!(|i| i.set_text(text), !Check | Submeun);
+/// ```
+///
+/// #### Example
+///
+/// ```ignore
+///  let rid = 23;
+///  let kind = ItemKind::Check;
+///  let resources_table = app.manager.resources_table();
+///  do_menu_item!(|i| i.set_text(text))
+/// ```

+/// ```ignore
+///  let rid = 23;
+///  let kind = ItemKind::Check;
+///  let resources_table = app.manager.resources_table();
+///  match kind {
+///  ItemKind::Submenu => {
+///    let i = resources_table.get::<Submenu<R>>(rid)?;
+///    i.set_text(text)
