Actually, this appears to fail already, at least in 9.2.2:

=> select * from (values (1)) v(a) where v.a in (select x from (values (2)) v2(a),
->                     generate_series(1,a) x);
ERROR:  function expression in FROM cannot refer to other relations of same query level
LINE 2:                     generate_series(1,a) x);                                             ^

Unless it's something else that you were referring to...?
Thanks,
