I've done a rapid reading, 
in the objec-model 
primitive class Point implements Serializable 

should be 
primitive Point implements Serializable 

"value" is a modifier but "primitive" is a top level type. 

The design in part 3 is cool, because if i'm not mistaken, you can implement value classes without the support of Qtype in the classfile.
