So what exactly is coming with extended C++ support?

-GC
-no meta programming vs meta programming
-defaults to ref semantics C# vs value semantics C++
-C++ supports unique types, C# does not
-C# lambda automatic/GC, C++ lambda fully customized via capture 
list

  Sorry no clue what C++ features will be supported! Just glad 
that a language is acknowledging how important it is to inter-op 
with C++ for once.

  I don't really think this is the same situations. I don't think 
C# is any higher level than C++. Having a GC does not make it 
automatically a higher level language, nor does it make it more 
"productive".

  That said, I think it is much easier to be productive in C# if 
you are starting from scratch, but with the proper setup & in 
depth knowledge of C++, it is every bit as productive(especially 
in games, where things like GC end up as more of a burden).
