Why is that better than just getting `sizeof(* foo)`? Even with typedef, I can see this happening in the future:

    typedef int thing_t;
    ...
    thing_t *foo_internal;
    thing_wrapper_t *foo;
    // code
    foo = malloc(sizeof(thing_t));

If you do:

    foo = malloc(sizeof(*foo));

That's at least always on the same line.
