And I'd like to see proto_tree_add_XXX_item() routines that add an item with a particular type *and* take a pointer argument and return the value for the item through that pointer; that could replace

         xxx = tvb_get_XXX();
         proto_tree_add_XXX(..., xxx);

combinations and

         xxx = tvb_get_XXX();
         proto_tree_add_item(...);       /* re-fetches the item value */

with

         proto_tree_add_XXX_item(..., &xxx);

That would be neat, though we would have to be careful with our
fast-path handling, since we should return the value regardless.

Yeah, Anders asked about doing that a while back [hmm, some years ago] and I decided that it was going to be too much code (at least for my patience level) to get around TRY_TO_FAKE_THIS_ITEM() and friends.
