I figure eventually there's going to be a compiler version annotation on 
every class to save Java from its legacy burden.

@Compiler(language="java", version=12)


My new job uses Java 8 and I have mixed feelings.  Lambdas are more 
efficient than anonymous classes but the syntax is completely FUBAR.  
Multiple method signatures + Generics + functional interfaces results in 
more compilation permutations than the compiler is willing to guess.  
Last time I checked, it was giving up after trying about 10.  Half the 
methods in the stream package don't compile reliably for Maps.  Imagine 
something more complicated producing hundreds or thousands of possible 
permutations and having more than one possible solution.


C++ had to kill off some old features that brought its evolution to a 
temporary halt.  Java must do the same or die.
