Re: ELI5: newruntime and arc

[ducktape]

All that makes sense and is very exciting! I think some easily sharable 
examples will help these features make a splash when they do hit a more 
finished state. If my understanding of newruntime && arc are correct (I skipped 
C++ and went straight to Rust), then these features are a Big Deal, not just 
from a technical standpoint, but also a PR standpoint.
