It would be better if 8 bit or 16 bit systems provide some sort 
of segmented pointer such that allocating 32 bit would be require 
a `struct Ptr {ubyte firstSegment, ubyte secondSegment, ubyte 
thirdSegment, ubyte fourthSegment}` on 8 bit architecture and 
`struct Ptr {ubyte firstSegment, ubyte secondSegment}` on 16 bit 
systems.
