Reference implementation

[Paul Benedict]

Neal,

Thank you for raising this point again!

It was admitted the current diamond operator implementation is
incomplete compared to the "complex/full" solution. It was also
admitted the partial solution is not a "true subset" of the "complex"
solution. With that said, I am concerned the partial solution will
infer somethings in JDK 7, but a later JDK using the "complex"
solution would infer differently or invalidate inferences of the
partial solution. Joe, is that possible?

Paul
