That's for the readability.
Let me give you an example:
Elm_Object_Item *it1, *it2; // it1 is a menu item, it2 is a toolbar item.
elm_object_item_xxx(it1, ...);
elm_object_item_xxx(it2, ...);
vs
Elm_Object_Item *toolbar_item, *menu_item;
elm_object_item_xxx(menu_item, ...);
elm_object_item_xxx(toolbar_item, ...);
1st one is more confusing. We have to trace to see what widget item
we're handling.
But 2nd one is more descriptive, clearer, and easy to debug. We can
guess what widget item we're handling by variable name :)
As Hermet said, this can be decided by each application programmer,
but I also prefer the latter.
Thanks.
