Compose T7 with all

(dolist (x '(t1 t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 t12))
   (print (list 't7 (list x (t7 (funcall x r))))))

We get the results:

(T7 (T1 ("babaBABAAbb" . "AAbbb"))) 
(T7 (T2 ("bbabABAB" . "AAbbb"))) 
(T7 (T3 ("baabaBABAB" . "AAbbb"))) 
(T7 (T4 ("babaBABB" . "AAbbbabaBAB"))) 
(T7 (T5 ("babaBABB" . "BBBaa"))) 
(T7 (T6 ("babaBABB" . "AbbbA"))) 
(T7 (T7 ("bbabaBABBB" . "AAbbb"))) 
(T7 (T8 ("babaBABB" . "bAAbb"))) 
(T7 (T9 ("bbaBABaB" . "AAbbb"))) 
(T7 (T10 ("babaBABB" . "AAAbbba"))) 
(T7 (T11 ("abaBAB" . "AAbbb"))) 
(T7 (T12 ("babaBABB" . "BAAbbbb")))
