I classify methods according to 
A. those just modify pass in objects and  use temprorary variables on the stack or static allocated buffers on the heap before invoked by messages.
This class is safe for run-time polymorphism.
 
B. those  have to generate  any new non-temporary object to be assigned to some objects in return, somewhat like the heap hog eater in this calss. 
If any method in this class calls a method in this class, then it becomes a 
memrory hog very easily especially in the recursive way.
