MAYBE

Problem:
 strict:
  app(nil(),k) -> k
  app(l,nil()) -> l
  app(cons(x,l),k) -> cons(x,app(l,k))
  sum(cons(x,nil())) -> cons(x,nil())
  sum(cons(x,cons(y,l))) -> sum(cons(plus(x,y),l))
  sum(app(l,cons(x,cons(y,k)))) -> sum(app(l,sum(cons(x,cons(y,k)))))
  plus(0(),y) -> y
  plus(s(x),y) -> s(plus(x,y))
 weak:
  cons(x,cons(y,l)) -> cons(y,cons(x,l))
