[development] load node globally

Hello All, Since I see so many node loads in block visibility and in modules that do $node manipulations and so forth, which would make me think that sometimes many node loads might occur on some pages and tens perhaps when you add contributed modules on that, I was wondering why not just load $node globally on node/<num>/* pages like we do with $user to avoid any extra node_loads? Developers would only need to global $node and it would either be null or populated and ready. Before creating a patch for a *possibly* terrible idea, I thought I'd raise a stick and see if it gets shot :D -- Ashraf Amayreh http://aamayreh.org
