Looking again, I think code is correct as-is (am not sure about the depth adjustment though).

Stylistically, it is different from the other blocks w_complex_object() that always have a "return" after setting p->error.  The new code jumps to "anyset_done" and then falls through the "elif" block rather than issuing a "return".

Since nothing else happens below the if-elif-else chain, this is without consequence.
