Walter and Andrei have, in the past, stated many times that they 
believe Rust's approach to the memory safety problem is too 
complex and not a good fit for D. They have been exploring 
alternative solutions for a while now, and will probably announce 
something eventually.

Nothing significant gets added to the language, runtime, or 
standard library without their approval - no matter how popular 
it is with the community.

So, make sure that you get explicit pre-approval from them before 
you waste your time, unless everything you want to do can be 
implemented as a normal stand-alone DUB package.
