Carbon will not have a GC. It will also not have Rust semantics 
as the checker would be too slow, at least that is what has been 
said.

Carbon will have more limited generics than C++, so that the 
"template" can be selected based on the signature constraints 
without instantiating it. In that sense it is simpler than C++.

I think they actually aim for faster than C++. I assume faster 
compilation and perhaps more clever optimizations, but I don't 
know if it is realistic to expect any significant speedups for 
performance oriented code. Perhaps for naive code?

I would hope that it would be possible to use ARC, but I don't 
think this will come from Google. I suspect ARC is "too slow" for 
their use cases?

I would hope that they make the compiler modular so that things 
like ARC can be "plugged" in by a third party.
