# [plt-scheme] is this a deep list ?

Since this is my first posting i want to first thank the authors of
htdp for such a wonderful book.
I also want to confirm to you that i am not a "student" in any school
or college.
>*From ex 11.2.4
*A deep-list is either
1. s where s is a symbol or
2. (cons dl empty) where dl is deep-list
Now from 1 we can say 'doll is a deep-list
>*From 2 we can say (cons 'doll empty) is a deep list
*>*From 2 we can say (cons (cons 'doll empty) empty ) is a deep list
*since it is in the form (cons dl empty)
Now is this a deep list , (my understanding is that it is not
deep-list as per defination) :
(cons (cons 'doll (cons 'robot empty)) empty)
why , well for it to be a deep-list the middle part has also to be a deep-list .
But middle part is in the form (cons 'doll dl) i.e cons follwed by a
symbol followed by a deep-list and as per defination
there is no match , hence it is not a deep-list.
Please confirm if my reasoning is correct for this deep-list as per
defination given in the book
Thank you
