Now:

?- dif(A,B),A=A*B*[],B=C*C*a.
   A = A*(C*C*a)*[], B = C*C*a, .

Back to:

?- A=A*B*[],B=C*C*a,dif(A,B).
   A = A*(C*C*a)*[], B = C*C*a.
?- dif(A,B),A=A*B*[],B=C*C*a.
   A = A*(C*C*a)*[], B = C*C*a, dif:dif(A*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[]*(C*C*a)*[],C*C*a), unexpected.
