Given that Sean Baxter already has lifetimes in Circle that work very similarly to Rust's, I'm skeptical that the very similar D language wouldn't be able to express the same thing.
Generously, you've confused somebody saying they're interested in working on a problem with them having a working solution to the problem.
Circle does not, in fact, have working Rust style lifetimes. Sean splits the Circle documentation into features which work and "Research" features Sean is working on and lots of interesting ideas, including lifetimes, are in the second category. Maybe Circle will implement them some day, or maybe it will not.
