T changes its inner encapsulated states. Period. It is no 
different that properties that calculate result on the fly, like 
range.empty (which is good property usage).

Array.length allocates. Takes from some global resources, takes 
some considerable time, calls some global allocating function.

For me it is a crucial difference that pushes symbol to the world 
of functions.
