The pattern of:
auto tab = get_tab();
auto walker = get_walker();
if (tab && walker) {
if (auto node = walker->dom_node(node_id)) {
delegate().do_something(tab->description(), node);
}
}
Is getting a bit unergonomic and is often repeated. This patch just adds
a helper to WalkerActor to do most of this work, so now we have:
if (auto node = WalkerActor::dom_node_for(get_walker(), node_id)) {
delegate().do_something(node->tab->description(), node);
}
