The size of the list would be something like $#{$item:contained_in}
the size of the list is not a property of the item, some indirection
resolution would be required.
I think :n because that allows lazy lists to be functions of integers,
which were always I<f(n)> in algebra class.
You could access n directly within a HOF lazy list with ${ME:n}.
Shifts would increment such a list's $WE[0]:n value, until it is reset.
(addendum to the $ME idea --- containers are refered to inside themselves
as [@%]WE -- thoughts?)
