We learn the following

atom - rank 0, shape: empty list
list - rank 1, shape: list with 1 integer
table - rank 2, shape: list with 2 integers
report - rank 3, shape: list with 3 integers

But then we need to disrupt this smooth flow:

empty-list - rank 1, shape: 0

All other shapes are lists. But the empty list has an integer as its shape.

Just observing
