diamond operator & implementation strategies (v3)

[Paul Benedict]

Maurizio,

Great response. Thank you. I am going to infer (pun) the 'full-complex'
approach is outside the scope of Project Coin. Since it seems the 'simple'
approach has your favor, my advice for you is to apply great caution to the
JLS changes as to make them forward-compatible. Any inference must be
identically solved by the 'full-complex' approach, otherwise it shouldn't be
inferred. I think it would be a bad idea for call sites to get resolved
successfully (and differently) between Java 7 and Java 8+.
