 From an ASM point of view, both using an array instead of nested 
structures and optimizing multiple levels of the same kind is fine. The 
important point is that all paths should be "from outside to inside" 
(e.g. for nested types, the path should go from outer to inner, not the 
other way around as proposed in the Nov 7 specification).
